Imagine you have to do something that you really don't want to do. Say, your girlfriend drags you to the opera or something. Then, just as the singing begins, someone comes over and punches you in the nuts. So you're doing something that you really didn't want to anyway, but there's no way you could have guessed how truly painful the experience would be.
And so goes the DVD podBLAST of "Rollerball".
Though, we must admit, we've never been to an opera that featured Rebecca Romjin naked.
