Back to the Future Trilogy

The series continues as Doc Brown travels with Marty to the year 2015 where he has discovered Marty's family is in ruins. Marty buys a sports almanac containing the outcomes of 50 years worth (1950-2000) of sporting events. However, Doc catches him and throws the almanac in the trash, where the aged Biff Tannen finds it. While Marty and Doc are at Marty's future house, Old Biff steals the DeLorean time machine and gives the book to himself just before he goes to the dance at the end of the first movie. When Doc and Marty return to 1985, they find that Biff has used the almanac's knowledge for financial gain, which allows him to turn Courthouse Square into a 27 story casino, "own" Hill Valley, get away with the murder of Marty's father, and later marry Marty's mother. Marty learns that Biff was given the book by old Biff on November 12, 1955, so he and Doc go back to that date in order to steal the almanac from Biff before he can use it to destroy their lives. They accomplish this in a complex fashion, often crossing their own past-selves' paths. When the duo are about to travel back to 1985, a lightning bolt strikes the DeLorean and scrambles the time circuits, sending Doc back to 1885 and leaving Marty stranded once again in 1955.

After finding out that Doc Brown is trapped in 1885, Marty sets out to find the 1955 Doc to help him fix the DeLorean (which has been waiting for him in a mineshaft for 70 years) and restore it to working order. Learning that Doc gets shot in 1885, Marty travels back in time to save Doc (who has become a blacksmith) and bring him back to the future. Unfortunately, an arrow has ripped a hole in the fuel line, emptying the gas tank and rendering the DeLorean engine useless. Furthermore, Doc falls in love with schoolteacher Clara Clayton, and considers staying in 1885. Marty must convince Doc to come back with him and find a way to get back to his time before it's too late. After several dramatic action scenes involving a speeding locomotive, Marty returns to 1985 in the restored DeLorean. It appears on a train track as planned, and Marty jumps out just in time to see the DeLorean time machine destroyed by a modern train. He worries that Doc has been lost in the past forever, when suddenly Doc Brown appears in a new time machine, modeled after a locomotive. He introduces Marty to Clara (to whom he is now married) and his two sons, Jules and Verne. When Marty asks if Doc and his family are going to the future, Doc replies that he's already been to the future. The locomotive flies across the sky and disappears, ending the trilogy.

In July 1997, Universal Studios announced that Back to the Future would be one of their first 10 releases to the new format, though it ended up being delayed for five years. It was finally released in 2002 in widescreen, with a black box. In the USA, a fullscreen version was also released.

On October 21, 2008, BTTF.com broke the story that Universal will be releasing each of the "Back to the Future" films individually. The DVDs were released on February 10, 2009. "Back to the Future" became a 2-disc set featuring the documentary "Looking Back to the Future" and "Back to the Future: The Ride.

In June 2008, a special screening of the trilogy was held in Celebration, Florida. Bob Gale told the crowd they were seeing the digitally remastered version that was going to be used for the Blu-ray version of the movies. Gale also spoke to potential supplemental features on a Blu-ray version of the trilogy, saying only that never-before-seen bonus materials may appear, though he stopped short of offering any specifics. On June 28, 2010, Universal announced that the Blu-ray edition of the films would be released on October 26, 2010, twenty-five years to the day from the date of the fictional events from the first film.
