My dad and I watched Richard Donner's Superman on television in the '80s many, many times. We don't have much in common when it comes to our tastes in film, but we've always seen eye to eye on Superman and Superman II, and I'm grateful for that.
The Goonies might be the movie that I've watched the most with friends, Scrooged is my favorite Bill Murray movie (or at the very least it's tied with Ghostbusters), and The Twilight Zone's Nightmare at 20,000 Feet was my introduction to the awesome work of Richard Matheson. I've never seen a Lethal Weapon movie, though.
Anyway, /rambling. Rest in peace, Mr. Donner.
