12:01 P.M.

"12:01 PM" was first adapted into an Academy Award–nominated[4] 1990 short film starring Kurtwood Smith. Directed by Jonathan Heap, it originally aired on the cable television network Showtime in 1990 as part of their 30-Minute Movie anthology series.

In this version, Kurtwood Smith plays Myron Castleman, an everyman-type who keeps repeating the same hour of his life, from 12:01pm to 1:00pm. The character is fully aware that the time loop is occurring, and nobody else appears to be aware of it. Each time the hour resets, Myron retains his memory (or as the film puts it, his consciousness), and despite his best attempts to understand what is happening, he ultimately realizes that he is entirely helpless to prevent the time bounce. Myron cannot even break the loop by killing himself, as he reappears, alive, at the next iteration; he is trapped in the loop for eternity.

This version has not been released on DVD or VHS in the United States, but 12:01 PM is available on DVD in the UK,[5][6] collected with seven other short films.

12:01 is an adaptation of the same short story, produced as a television movie in 1993. It stars Helen Slater, Jonathan Silverman, Jeremy Piven, and Martin Landau, and it originally aired on the Fox Network in the United States. In this version, Silverman’s character, Barry Thomas, keeps reliving the same 24-hour period (which in this case restarts at one minute past midnight, rather than midday as in the other versions). Slater plays his romantic interest, and Piven provides comic relief as his best friend. This version differs from the short film in that it features a much lighter and more comedic tone, and that the protagonist ultimately finds a way to correct the time loop over the course of the film. This version was released on DVD in the United States on November 28, 2006.
