Rat Race
The plot: An eccentric casino owner challenges a group of people to a race across America - the first one there gets $2,000,000 cash.The good: Fantastic cast including Rowan Atkinson, Breckin Meyer (Josh from Road Trip), Cuba Gooding Jr., Whoopi Goldberg, Seth Green and John Cleese. Very funny.
The bad: While it is a funny comedy, it's a fairly standard Hollywood comedy layout, there isn't much original here. Lots of bad science too.
Conclusion: It is worth a watch just because of the amount of great people in the firm. You aren't missing anything if you don't see it though.
