I've only seen two - Logan's Run and Demolition Man.
I actually really liked Demolition Man, some good action combined with some pretty good satire. Plus it had Sandra Bullock.
Those are the same two that I have seen. Logan's run had Farrah.
Sandra Bullock was definitely hot in Demolition Man. I also remember it being the first movie I saw with Denis Leary.
One of the scenes I remember most from Demolition man is the scene in the under ground where he buys the burger because of the way the audience reacted. I went on opening night and the place was packed. When the scene where Stallone bought the burger was shown there were two separate and distict times when the audience laughed. The first laugh came from the part of the audience who heard the description and understood what the cook told him. A few seconds later the part of the crowd who understood English laughed because Stallone told us that he had just bought a rat burger. The crowd must have been about half and half since the reaction from both sounded about the same.
The reason it stuck in my mind was because I knew that if I still lived in the midwest when I saw it the reaction would have only been when Stallone told us what he had just bought.
