Back to the Future Part II

On October 26, 1985, Dr. Emmett Brown arrives unexpectedly in the DeLorean time machine at Marty’s front yard after the events of the 1st film. Doc persuades Marty McFly and his girlfriend, Jennifer Parker, to travel to the future with him[N 1] and help their future children, with Biff Tannen witnessing their departure. They arrive on October 21, 2015, where Doc electronically incapacitates Jennifer and leaves her asleep in an alley, explaining that she should not have too much knowledge of future events. He has Marty pose as his son and lookalike Marty Jr. to refuse an offer to participate in a robbery with Biff's grandson Griff, thus saving Marty Jr. from prison.

Marty switches places with Marty Jr. and refuses Griff's offer, but Griff goads Marty into a fight, and a subsequent hoverboard chase ensues. Griff and his gang are arrested, saving Marty's future children. Before rejoining Doc, Marty purchases an almanac containing the results of major sporting events from 1950 to 2000. Doc discovers it and warns Marty about profiting from time travel. Before Doc can adequately dispose of it, they are interrupted by the police, who have found Jennifer incapacitated and are taking her to her 2015 home. They pursue, as does the elderly Biff, who has overheard their conversation and retrieved the discarded almanac.

Jennifer wakes up in her 2015 home and hides from the McFly family. She overhears that her future self's life with Marty is not what she expected, due to his involvement in an automobile accident. She witnesses Marty being goaded by his co-worker, Douglas Needles, into a shady business deal, resulting in Marty's firing. Jennifer tries to escape the house but faints after encountering her 2015 self. While Marty and Doc attend to her, Biff steals the time machine to give the almanac to his younger self, then returns to 2015. Marty, Doc, and an unconscious Jennifer return to 1985, unaware of Biff's actions. They leave Jennifer on her front porch.

The 1985 they return to has changed dramatically, with Biff now one of the country's wealthiest and most corrupt men. He has turned Hill Valley into a chaotic dystopia, secretly killed Marty's father, George, in 1973, and forced Marty's mother, Lorraine, to marry him. Doc has also been committed to a mental hospital. Doc deduces that old Biff took the time machine to give his younger self the almanac, and Marty learns from the alternate 1985 Biff that he received it on November 12, 1955. Biff tries to kill Marty, but Marty flees and travels to 1955 with Doc.

Marty secretly follows the 1955 Biff and watches him receive the almanac from his 2015 self. Marty then follows him to the high school dance, carefully avoiding interrupting the events from his previous visit. After several fruitless attempts, Marty finally gets the almanac, leaving Biff to crash into a manure truck. Marty burns the almanac, nullifying the changes to the timeline that it had caused, as Doc hovers above in the time machine. Before Marty can join him, the DeLorean is struck by lightning and disappears. A Western Union courier arrives immediately after and delivers a letter to Marty; it is from Doc, who explains that the lightning strike transported him 70 years in the past to 1885.[N 2] Marty races back into town to find the 1955 Doc, who had just helped Marty to return to 1985. Shocked by Marty's sudden reappearance, Doc faints.

Director Robert Zemeckis said that, initially, a sequel was not planned for the first film, but its huge box office success led to the conception of a second installment. He later agreed to do a sequel, but only if Michael J. Fox and Christopher Lloyd returned as well. With Fox and Lloyd confirmed, Zemeckis met with screenwriting partner Bob Gale to create a story for the sequel. Zemeckis and Gale would later regret that they ended the first one with Jennifer in the car with Marty and Doc Brown, because it required them to come up with a story that would fit her in, rather than a whole new adventure.[4]

Gale wrote most of the first draft by himself as Zemeckis was busy making Who Framed Roger Rabbit. At first, the film's third act was to take place in 1967 where Lorraine was a flower child protesting the war and George was a college professor at Berkeley, but Zemeckis later stated that the time paradoxes of it provided a good opportunity to go back to 1955 and see the first film's events in a different light. While most of the original cast agreed to return, a major stumbling block arose when negotiating Crispin Glover's fee for reprising the role of George McFly. When it became clear that he would not return, the role was rewritten so that George is dead when the action takes place in the alternative version of 1985.[4]

The greatest challenge was the creation of the futuristic vision of Marty's hometown in 2015. Production designer Rick Carter wanted to create a very detailed image with a different tone from the film Blade Runner, wishing to get past the smoke and chrome. Carter and his crew spent months plotting, planning, and preparing Hill Valley's transformation into a city of the future.[5] Visual effects art director John Bell stated they had no script to work with, only the indications that the setting would be 30 years into the future featuring "something called hoverboards".[6]

When writing the script for Part II, Gale wanted to push the first film's ideas further for humorous effect. Zemeckis said he was somewhat concerned about portraying the future because of the risk of making wildly inaccurate predictions. According to Gale, they tried to make the future a nice place, "where what's wrong is due to who lives in the future as opposed to the technology" in contrast to the pessimistic, Orwellian future seen in most science fiction.[4] To keep production costs low and take advantage of an extended break Fox had from Family Ties (which was ending its run when filming began), it was shot back-to-back with sequel Part III.[7]

Two years were needed to finish building the sets and writing the scripts before shooting could begin. During filming, the creation of the appearance of the aged characters was a well-guarded secret, involving state-of-the-art make-up techniques. Fox described the process as very time-consuming: "it took over four hours, although it could be worse".[4] Principal photography began on February 20, 1989.[7] For a three-week period near the end of the filming, the crew split and, while most remained dedicated to shooting Part III, a few, including Gale, focused on finishing its predecessor. Zemeckis himself slept only a few hours per day, supervising both films, having to fly between Burbank, where it was being finished, and other locations in California for Part III.[8]

The film was considered one of the most ground-breaking projects for Industrial Light & Magic. It was one of the effects house's first forays into digital compositing, as well as the VistaGlide motion control camera system, which enabled them to shoot one of its most complex sequences, in which Fox played three separate characters (Marty Sr., Marty Jr., and Marlene), all of whom interacted with each other. Although such scenes were not new, the VistaGlide allowed, for the first time, a completely dynamic scene in which camera movement could finally be incorporated. The technique was also used in scenes where Fox, Thomas F. Wilson, Christopher Lloyd, and Elisabeth Shue's characters encounter and interact with their counterparts.[4] It also includes a brief moment of computer-generated imagery in a holographic shark used to promote a fictional Jaws 19, which wound up unaltered from the first test done by ILM's digital department because effects supervisor Ken Ralston "liked the fact that it was all messed up."[6]

Animation supervisor Wes Takahashi, who then was the head of ILM's animation department, worked heavily on the film's time travel sequences, as he had done in the original film and in Part III.[9][10] As Part II neared release, sufficient footage of Part III had been shot to allow a trailer to be assembled. It was added to the conclusion of Part II before the closing credits, as a reassurance to moviegoers that there was more to follow.[11]

Replacement of Crispin Glover

Crispin Glover (pictured in 2012) did not reprise his role as George McFly in Back to the Future Part II, and was replaced by Jeffrey Weissman.

Crispin Glover was asked to reprise the role of George McFly. He expressed interest but could not come to an agreement with the producers regarding his salary. He stated in a 1992 interview on The Howard Stern Show that the producers' highest offer was $125,000, less than half of what the other returning cast members were offered. Gale has since asserted that Glover's demands were excessive for an actor of his professional stature at that time.[11] In an interview on the Opie and Anthony show in 2013, Glover stated that his primary reason for not doing Part II was a philosophical disagreement on the film's message; Glover felt the story rewarded the characters with financial gain, such as Marty's truck, rather than love.[12]

Rather than write George out of the film, Zemeckis used previously filmed footage of Glover from the first film as well as new footage of actor Jeffrey Weissman, who wore prosthetics including a false chin, nose, and cheekbones to resemble Glover. Various techniques were used to obfuscate the Weissman footage, such as placing him in the background rather than the foreground, having him wear sunglasses, and hanging him upside down. Glover filed a lawsuit against the producers of the film on the grounds that they neither owned his likeness nor had permission to use it. As a result of the suit, there are now clauses in the Screen Actors Guild collective bargaining agreements stating that producers and actors are not allowed to use such methods to reproduce the likeness of other actors.[13] Glover's legal action, while resolved outside of the courts, has been considered as a key case in personality rights for actors with increasing use of improved special effects and digital techniques, in which actors may have agreed to appear in one part of a production but have their likenesses be used in another without their agreement.[14][15]

Replacement of Claudia Wells

Claudia Wells' scene at the end of Back to the Future (top) was reshot with Elisabeth Shue for the beginning of Part II (bottom).

Claudia Wells, who had played Marty's girlfriend Jennifer Parker in the first film, planned to reprise her role, but turned it down due to personal reasons. The producers cast Elisabeth Shue instead, which involved re-shooting the closing scenes of the first film for the beginning of Part II. The re-shot sequence is a near shot-for-shot match with the original, with only minor differences: for example, Doc noticeably hesitates before reassuring Marty that his future self is fine – something he did not do in the first film. Marty is also wearing a watch in the second film whereas he was not in the first.[16][17]

Wells returned to acting with a starring role in the 2008 independent film Still Waters Burn. She is one of the few cast members not to make an appearance within the bonus material on the Back to the Future Trilogy DVD set released in 2002. However, she is interviewed for the Tales from the Future documentaries in the trilogy's 25th anniversary issue on Blu-ray Disc in 2010. In 2011, she finally had the opportunity to reprise her role from the first film, 26 years after her last appearance in the series, by providing the voice of Jennifer for Back to the Future: The Game by Telltale Games.[18]

Though the filmmakers did research contemporary predictions by scientists on what might occur by 2015, Zemeckis has said that the film was not meant to be a serious attempt at predicting the future. In 2010, he commented, "For me, filming the future scenes of the movie were the least enjoyable of making the whole trilogy, because I don't really like films that try and predict the future. The only ones I've actually enjoyed were the ones done by Stanley Kubrick, and not even he predicted the PC when he made A Clockwork Orange. So, rather than trying to make a scientifically sound prediction that we were probably going to get wrong anyway, we figured, let's just make it funny."[20] Similarly, Gale said, "We knew we weren't going to have flying cars by the year 2015, but God we had to have those in our movie."[21]

However, the film did correctly predict a number of technological and sociological changes that occurred by 2015, including: the rise of ubiquitous cameras; use of unmanned flying drones for newsgathering; widescreen flat-panel television sets mounted on walls with multiple channel viewing; smart home technology; video chat systems; hands-free video games; talking animated billboards; wearable technology; tablet computers with fingerprint scanners and head-mounted displays.[22][23] Payment on personal portable devices is also depicted. Although payment by thumbprint is not widely used, fingerprint scanning is in use as security at places such as airports and schools, and electronic payment with fingerprint scanning as a security feature is deployed for Apple Pay.[23]

Other aspects of the depiction of the future had not come to pass by 2015, but efforts were made to replicate the technology advances.

Luxor Taxi based on 1972 Citroën DS

The film shows Marty putting on Nike "Air Mag" tennis shoes with automatic shoelaces. Nike released a version of their Hyperdunk Supreme shoes, which appear similar to Marty's, in July 2008. Fans dubbed them the Air McFly.[24] In April 2009, they filed the patent for self-lacing shoes, and their design bears a resemblance to those worn by Marty in the film.[25] In 2010, a fan named Blake Bevin created shoes that tie themselves.[26] Though Nike had made a very limited quantity of Air Mags in the same style as the movie, they stated in September 2011 that their consumer-line MAG line of shoes would not feature the self-lacing feature shown in it.[27][28] Tinker Hatfield, one of the shoe's designers, indicated in 2014 that they would introduce shoes with power-lacing technology the following year, 2015.[29] In March 2016, Nike unveiled the HyperAdapt 1.0 shoe, a consumer-market model of the Air Mag which features the same self-lacing technology used for the commemorative Air Mags; these were put on sale in limited quantities in late 2016.[30]

The producers created a futuristic flying car to depict a typical taxi cab in the future world of 2015. This taxi was based on the Citroën DS.[31]

The concept of the hoverboard—a skateboard that can float off the ground—has been explored by various groups since the release of the film. Attempts similar to hoverboats, which blast air at the ground, have been demonstrated,[32] with a 2021 record distance of 275 meters (902 ft).[33] A different type is the MagBoard, developed by researchers at the Paris Diderot University. It uses a large superconductor plate on the bottom cooled with liquid nitrogen as to achieve the Meissner effect and allow it to float over a special track; it was shown capable of carrying the weight of a human in its practical demonstration. However, the requirement to run the superconductor at higher, more ambient temperatures prevents this from becoming practical.[34][35] In March 2014, a company named HUVr Tech purportedly demonstrated a working hoverboard along with several celebrities including Lloyd, though this shortly was revealed as a hoax created by the website Funny or Die.[36] Self-balancing 'hoverboards' became popular in 2015 even though they do not hover above the ground.[37]

In the 2015 scene, the film imagines the Chicago Cubs winning the 2015 World Series against the fictional Miami-based Gators, referring to the Cubs' longstanding failure to win a championship. In the actual 2015 season, the Cubs qualified for the postseason, their first postseason appearance since 2008,[38] but lost the National League Championship Series (not the World Series) to the New York Mets on October 21, 2015, which coincidentally was the same day as "Back to the Future Day," the day Marty McFly arrived in 2015 in the film.[39] Despite losing in 2015, one year later the Cubs did win the 2016 World Series against the Cleveland Indians;[40] the official Twitter feed for the Back to the Future franchise tweeted out that Marty & Doc's time-traveling caused "a rift in the space-time continuum" that led to the 1994 strike (and subsequent cancellation of the 1994 World Series), thus delaying the accurate prediction by a year.[41] In the real 2015 World Series, the Kansas City Royals defeated the Mets to win their first World Series championship since 1985, the year which Marty and Doc time traveled in the film. As for the fictional Miami team, when the film was made, Florida did not have a Major League Baseball team,[42] but has since gained two: the Florida Marlins (now the Miami Marlins) in 1993 and Tampa Bay Devil Rays (now the Tampa Bay Rays) in 1998. While each team has made two appearances in the World Series (the Marlins winning in 1997 and 2003, and the Rays losing in 2008 and 2020), neither qualified for the postseason in 2015.

The soundtrack was released by MCA Records on November 22, 1989. AllMusic rated it four-and-a-half stars out of five.[64] Unlike the previous soundtrack, it contains only a musical score by composer Alan Silvestri. None of the vocal songs featured throughout the film are included. On October 12, 2015, Intrada Records released the complete score of Back to the Future Part II in a 2-disc set including early scoring sessions and alternative takes.
