Hill Valley (Back to the Future)

Other real-life shooting locations of Hill Valley landmarks include:[8]

• Doc's house in 1955 is the Gamble House in Pasadena, California. Doc's garage in 1985 was a façade set up next to a Burger King on North Victory Boulevard in Burbank, California.[11]
• Twin Pines/Lone Pine Mall is actually the Puente Hills Mall in Industry, California.
• Marty's Lyon Estates house in 1985 is actually at 9303 Roslyndale Avenue, Pacoima, California.
• The 1955 Lyon Estates field is actually along farmland between the city borders of Chino, California and Corona, California.
• Peabody's Twin Pines Ranch is really at Golden Oak Ranch, which is owned by The Walt Disney Company and used in many Disney productions.
• The houses of George McFly, Lorraine Baines, and Biff Tannen in 1955 are all in South Pasadena, California.
• The train that hit the DeLorean and the Futuristic Train were parked in Port Hueneme, California.
• John F. Kennedy Drive is actually Victory Boulevard in Burbank, California.
• The River Road Tunnel is actually Observatory Tunnel at Griffith Park in Los Angeles. The actual tunnel is only a fraction of the length of the one depicted in Part II.
• The Pohatchee Drive-In Theater where Marty initially travels from 1955 back to 1885 was not a real theater. It was constructed full-scale for the third film in Monument Valley, Utah (near the Arizona/Utah border) and was torn down after that portion of filming was completed.
• Marty's race with Needles was shot on Doris Avenue in Oxnard, California.
• Hilldale in 1985 was filmed at Doris Avenue and Oxford Drive in Oxnard, California.
• Hilldale in 2015 was filmed at Oakhurst Street and Somerset Avenue in El Monte, California.
• Hill Valley High School was filmed at Whittier High School in Whittier, California.

The town of Hill Valley is depicted as having been first settled in 1850 and incorporated in 1865. By the 1880s, it was connected by railroad to San Francisco. Construction of a new county courthouse was well underway in 1885, the setting of Back to the Future Part III, in which a new clock was dedicated for the building. The Shonash Ravine Bridge was completed in the summer of 1886, around the same time the ravine was renamed Clayton Ravine in memory of Clara Clayton, a school teacher who died from falling into the chasm. However, in a revised timeline where Doc Brown saved Clara's life, the town renamed it Eastwood Ravine after Marty McFly's persona when it is believed that "Clint Eastwood" fell into the ravine.

By 1955, as seen in the first two Back to the Future films, the area around the courthouse has developed into the downtown of Hill Valley. In front of the courthouse is a grass-covered town square, with stores, two movie theaters (Essex and Town), and cafés on the surrounding streets. Downtown also features a Texaco station, a Bank of America branch, and a Studebaker dealership. A key moment in the town's fictional history takes place on Saturday, November 12, 1955, at 10:04 p.m. PST, when lightning strikes the courthouse's clock tower, freezing the clock at 10:04. The clock is never repaired and becomes a local landmark, left in its non-functional state at the behest of the Hill Valley Preservation Society. In the revised timeline, the broken piece of ledge from Doc Brown's successful attempt to channel lightning from the clock tower is likewise never repaired, as can be seen when Marty returns to 1985 and in 2015, but not in the alternate 1985.

In Marty's original timeline, many of the town square businesses have moved or closed down by 1985. The new businesses which replaced them include a second-hand shop, a yoga studio, and an adult book store, and the Studebaker dealership becomes a Toyota dealership (but is still owned by the Statlers), though the Texaco station and Bank of America branch remained. The Essex movie theater now shows porno movies while the Town Theater is used for church services, and the courthouse is in a state of disrepair, and at night at least one homeless person (called "Red" by Marty) sleeps on the town square park benches. The grassy park outside of the courthouse has been converted into a parking lot. "That was always one of the major elements of the story even in its earliest incarnation," screenwriter Bob Gale says in The Making of Back to the Future, "was to take a place and show what happens to it over a period of thirty years. What happened to everybody's home town is obviously the same thing. They built the mall out in the boonies, and killed all the business downtown, and everything changed."[13]

By the 21st century, the downtown area has experienced a revival as the courthouse has been converted into the Courthouse Mall. Businesses have begun to move back into and around the town square and the parking lot has been replaced by a pond. The clock on top of the courthouse is still preserved at 10:04 and the mall's logo is an illustration of a lightning bolt striking the clock tower. The Town Theater/Assembly of Christ building has been converted to an art museum with a mural painted on the front side of the building above the marquee. The Texaco station remains, while the Toyota dealership is now a Pontiac dealership, though in reality General Motors would discontinue the Pontiac brand in 2010 as part of its bankruptcy.

Signs that say "Welcome to Hill Valley" are seen in 1955, 1985 and 2015. Both 1955 and 2015 signs have symbols representing the Rotary, Kiwanis and Lions clubs. In addition, the 1955 sign has the logos of the YMCA, Jaycees, and Future Farmers of America while the 2015 sign has those of the Neighborhood Crime Watch eye logo and the 4-H Club clover logo. The "Welcome to Hill Valley" sign in 1985 does not contain any signage representing any clubs and mentions the name of Mayor Goldie Wilson. In the alternate 1985, Marty is seen walking over the sign, which has been knocked down and an 'E' has been spray painted over the 'I' in HILL VALLEY making the name HELL VALLEY. This sign does not display the name of the mayor but instead the words "A Nice Place to Live" as also seen in 1955. A sign referencing US Highway 395 is also shown next to the Town Square in 1955.

Twin Pines Mall is a shopping center located outside Hill Valley, where Doctor Emmett Brown first tests his time machine, making his dog Einstein the first time traveler in the world. The site where the mall was filmed for the movie is actually Puente Hills Mall, located in City of Industry, California. The J.C. Penney location seen in the movie has been shut down and is now occupied by a 24 Hour Fitness center. The mall's name changed to Lone Pine Mall after Marty went back to 1985, because he accidentally destroyed one of the two baby pine trees for which it was named as he fled an irate Old Man Peabody, whose barn the DeLorean had crashed into upon arriving in 1955.

In Back to the Future Part II, a nightmarish alternate version of Hill Valley (dubbed 1985A by Doc) is depicted complete with a partial history. Due to the influence of the powerful and corrupt Biff Tannen, gambling was legalized in 1979. Tannen's toxic waste reclamation plants were built downtown, polluting the air and leading to pollution alerts to be issued. All of the local businesses in the downtown area closed or relocated and were replaced with strip clubs, porn theaters, and brothels. Tannen also bought off the police. Consequently, crime increased and biker gangs settled in the city. Hill Valley's public schools burned down and the courthouse was converted into Biff Tannen's Pleasure Paradise Casino and Hotel. The clock on the courthouse still remains at 10:04, although despite the damage the Doc did to the tower's platform in 1955, for whatever reason, it now seems to have disappeared. Biff also murdered George McFly (Marty's dad) on March 15, 1973, so that he could marry George's wife Lorraine (Marty's mom) therefore making him a corrupt family man as well as town ruler. He also helped Richard Nixon remain President of the United States until at least 1985. Biff's effect on history affected the whole world – in this version of history, the Vietnam War was also still ongoing by May 1983.

According to the original script for Back to the Future Part II a partial view of the alternate 2015 was also to be depicted. By this time Biff now owns half the state of California with his influence having gained his son, Biff Jr., the seat of governor and they uphold their power and corruption with an army of large, powerful cyborg police officers, which now has its 5 star resort in what would have been the courthouse mall in 2015.

Another timeline, branching off the events of Back to the Future: The Game, sees Irving "Kid" Tannen, the father of Biff Tannen and a prohibitionism era mafioso, avoid his lengthy incarceration for illegal consumption and sale of alcohol. As such, in the alternate 1986 Biff Tannen has two brothers, and the Tannen family is a recognized crime family, ruling over Hill Valley with an iron grip.[14]

In yet another alternate history, still branching off the events of Back to the Future: The Game, a teen Emmett Brown, in 1931, fell in love with the young journalist Edna Strickland: as a result she married Emmett, convincing him to pursue sociological and political goals. She managed to win him over by keeping him interested in science, but in a manner that his scientific skills could be used to control people instead of using science to understand mysteries and for the betterment of humanity. As such, under "Citizen Brown"'s influence by 1985 Hill Valley is a technological dystopia, where Emmett Brown oversees a fascist regime, controlling every single activity of his citizens, routinely brainwashed and spied over. In this new Hill Valley, in a reversal of their usual roles, Marty McFly is a square, serious and devoted to Emmett Brown to a fault (as the "original" McFly is dismayed to discover) and Jennifer is a rebellious rocker, a wild child with an unpredictable streak. Also Lorraine is again a mildly obese, inebriated sad woman, George has reverted to be the loser he is in the first, original timeline (although his oppressor is big government instead of Biff). In addition, George reprises his "peeping Tom" activities as seen in Back to the Future, under the guise of monitoring security camera footage for Citizen Brown. Biff Tannen is now one part of the Citizen Plus program, brainwashed into obedience. Hill Valley now looks as a technological advanced marvel, owned by a now rich and powerful Emmett Brown, with even the iconic Town Hall replaced by a huge pane with the E. Brown Industries symbol. As a side note, since in this timeline Emmett Brown never developed time-travel technology, the events of the original series never took place, and the Eastwood Ravine is still known as the Clayton Ravine, as no one saved Clara from her death.[15]

The last attempt to fix the damages involved with the events of Back to the Future: The Game ends with even a more radical change, with Edna Strickland traveling under an assumed name to 1876 to act as a moral guide of the newly founded Hill Valley; however, after a failed confrontation with Beauregard Tannen, a Confederate soldier who built and founded the Palace Saloon, she accidentally causes a conflagration that consumes Hill Valley, turning it into a ghost town with herself as the only resident. Again, Marty and Doc manage to restore the continuity, that now however sports minor alterations: Arthur and Silvia, Marty's grandparents, prepone their marriage to 1931 (it was 1936 in the original timeline), Doc Brown spends more time in 1986 and less traveling through time, Kid Tannen is now reformed, married to Edna Strickland and having a better influence over Biff.[16]
