Death Race 2000 is my all time favorite B movie. Just the fact that you have two well known actors in lead rolls in the cheesy sci-fi flick makes it a must watch, but it had a good concept of what America could become someday.
The scary parts is a remake is in the works. I never saw the Rollerball remake, but all accounts I have heard have been negative. I cannot see how a remake of Death Race 2000 can match the cheese of the original. Maybe if they go for a more serious dark version it might work. If they go for the campy feel of the original it will fail. Heck, who could take the place of that awesome announcer/anchor guy.
If anyone is looking for more cheesy b-movies, try Frakinhooker. If you have not seen this 1990s b-movie, then rent it for a good laugh.
