This week we’re firing up the flux capacitor and heading back to 1985 with Back to the Future.

We talk Marty McFly, Doc Brown, and whether the time travel rules in this movie make any sense at all. Plus: Lorraine’s crush on her own son (yikes), Crispin Glover’s wonderfully weird George McFly, and why the Enchantment Under the Sea dance might be one of the best teen movie set pieces ever.

Along the way, we dig into the casting drama (sorry, Eric Stoltz), Michael J. Fox’s grueling schedule, and how a movie that almost didn’t get made became one of the biggest hits of the decade.

Rewatch it with us and decide: is Back to the Future still as timeless as we remember—or should it have stayed in 1985?
