Blade Runner, awesome sci-fi movie starting Harrison Ford & Rutger Hower. This movie still holds up today, even tho about 20-25 years old. You have to get this Shawn, totally not kidding.
Blue Thunder, Roy Schrider movie about a prototype helicopter project gone bad.
Jaws Classic must see if not done so in a while. Another Schrider movie "Were gonna need a bigger boat."
Shawshank Redemption like Tom said, I love this prison movie.
Beetlejuice, Wacky, funny, stupid movie with a great cast. For some reason, another movie I can watch repeatedly and not get tired of it.
Fast Times at Ridgement High Personal favorite, tells the Headbanger and normal story of high school in the 80s. I would be close to the Spicoli (Sean Penn) roll such as, "Hey buds, let's party". Again, this cast is phenomenal.
