Time Freak

If at first you don't succeed, build a time machine.

A warm, playful romantic comedy that uses time travel as a vehicle for exploring love, friendship, and the acceptance that you can't fix the past—only learn from it.

Stillman, a heartbroken physics student, builds a time machine when his girlfriend breaks up with him. Going back in time, he attempts to save their relationship by fixing every mistake he made—while dragging his best friend along in the process.
