Do The Twist

I saw an ad for State Of Play that promised "a twist you'll never see coming."

You know how to have a twist I'll never see coming? Don't tell me there's a twist coming.

The only film I can remember that got around the problem was The Crying Game. I'd heard there was a big twist. When one of the leads, Forest Whitaker, suddenly got run over, I figured that was it. Didn't seem like the biggest twist, but after that my guard was down, so when the actual twist came, it really worked.

Incidentally, the twist in State Of Play is so obvious the only way you won't see it coming is if you've never been to a movie before.
