1 Silence of the Lambs, every time....
2 Forbidden Planet - the blu-ray is awesome on a big screen
3 Golden Eye (of course) but any Roger Moore Bond film
4 Having seen the butch films people are listing, this will make me come across as an ever bigger h0mo (as if such a thing were possible): Grease and Little Shop of Horrors!
On a slightly different twist, some films that I've watched that much I can never see them again:
Everything Segal
Arnie's '90s stuff (except T2)
Most JCVD '90s stuff, but I was thinking of maybe watching Double Impact again just to see Cory kick ass
Aliens
