Back to the Future(1985)
Marty McFly just broke the time barrier. He's only got one week to get it fixed.
The brilliant first chapter of Robert Zemeckis' peerless Back to the Future trilogy. Marty McFly (Michael J. Fox) is blasted to 1955 in the DeLorean time machine invented by Doc Brown (Christopher Lloyd). There he bumps into his young mum (Lea Thompson) and dad (Crispin Glover) and finds himself mixed up in a time-shattering chain reaction that could destroy his own future and leave him trapped in the past.
