When he inadvertently gets in the way of his teenage parents' relationship, Fox has to figure out how to get them back together to insure his own eventual existence.

BACK TO THE FUTURE PART II, 1989, Universal, 108 min. Dir. Robert Zemeckis. Michael J. Fox and Christopher Lloyd return for a sequel that spends most of its running time not before or after the original story but at the same time.
