Oh my gosh, I am such a movie nut. My list would be 100 long but I'll try to narrow it down. I love 'It's a Wonderful Life", "Up", "Perfect Storm", "Gladiator" and "Sleepless in Seattle".
Midnight Cowboy, Wizard of Oz, Used Cars, and all of the Godzilla movies especially Godzilla versus Mothra. I Have always been a fan of horror movies but not the kind we see today that are full of violence and blood.
I meant to add I agree with Barbara G. Anything with Kevin Costner is good. And I love Godzilla and King Kong movies. I can handle today's horror movies, they just don't really scare me.
