I see someone mentioned Strange Brew, That was a good one.
I think my favorite is the original Gone in 60 Seconds (It was filmed on a low budget and without the permits and stuff).
I also liked the first Spielburg movie where the truck was trying to run the guy off the road... Can't think of the name? .... DUEL?
Oh and you'll probably think i'm nuts, but the Princess Bride is probably my 2nd favorite! (Anybody want a peanut?)
