Back to the Future

“He was never in time for his classes... He wasn't in time for his dinner... Then one day... he wasn't in his time at all.”

Marty McFly (Michael J. Fox) is yanked thirty years into the past when his friend Doc Brown (Christopher Lloyd) sends him back in a time machine built into a DeLorean. In 1955, his mother is falling for him instead of his father George (Crispin Glover). Marty has to steer his parents toward each other before he fades from existence, which means getting George to stand up to the town bully and teaching him to kiss.
