Back to the Future (1985)

High schooler Marty McFly (Michael J. Fox) doesn't have the most pleasant of lives. Browbeaten by his principal at school, Marty must also endure the acrimonious relationship between his nerdy father (Crispin Glover) and his lovely mother (Lea Thompson), who in turn suffer the bullying of middle-aged jerk Biff (Thomas F. Wilson), Marty's dad's supervisor. The one balm in Marty's life is his friendship with eccentric scientist Doc Brown (Christopher Lloyd), who at present is working on a time machine - set up in a DeLorean sportscar... Accidentally sent back into the 1950s, Marty on one hand has plenty to do to get back to the future again and on the other hand not to erase his future life by mixing up to much...
