In this classic sci-fi adventure from director Robert Zemeckis, eccentric inventor Doc Brown (Christopher Lloyd) turns a DeLorean into a time machine that inadvertently sends his young friend, Marty McFly (Michael J. Fox), 30 years into the past. While stuck in the 1950s, Marty disrupts his parents' destiny and risks throwing the time-space continuum completely out of whack. The only way back to 1985 now is to get mom and dad to fall in love all over again.
