Big cinema weekend, this one - there's Will Smith's giant monster movie still out, plus new releases like the Oscar-likely Sweeney Todd and the unstoppable Judd Apatow's new comedy Walk Hard.

But none of these movies topped the weekend box office. No. The top movie at the US weekend box office chart this week is National Treasure: Book Of Secrets, a sequel to a film that the majority of people forgot even existed about a day after it was released. But National Treasure: Book Of Secrets isn't just important because it topped the weekend box office - it's also important because it's a successful Nicolas Cage film, and that fact alone has turned our perception of the world upside down to such a hideous extent that we're half expecting Santa Claus to come down our chimney and crap in our mouths tonight.
