Back to the Future on an HBO channel. I missed the beginning, and came in right where Marty and the scientist are being chased by "Libyans". Right before he lands in the past.
I had of course seen this in 85 when it came out and thought it was a very fun well-done movie back then. And actually it holds up. Silly and broad in ways, and cliche, it still has an engaging plot and moves at a good pace, so I never got bored or irritated. I was always uncomfortable about the sexual attraction between Marty and his mother in the 50s, but other than that, it's a sweet fun flick.
