George Clooney, they say, is the perfect movie star. He's handsome, charming, socially aware, a critical darling and lightly self-deprecating.

Trouble is, nobody goes to see any of his movies. You may have thought that this instalment of the weekend box office would be all about Leatherheads, the knockabout screwball sports comedy that George Clooney stars in and directs.

But no - Leatherheads lost out at the weekend box office to last week's US weekend box office number one 21. George Clooney, then - officially not as good as shit films about maths that nobody could possibly come close to liking.

Kevin Spacey is a well-respected theatrical artistic director. This is mostly because all the films he's made lately have been cack.

It's true - look at K-Pax, Pay It Forward, The Shipping News, Fred Claus. Kevin Spacey can't even make a Superman movie these days without everyone thinking it's a bag of stupid donkey pubes.

But, hey, look at this - Kevin Spacey is in 21, and 21 is the number one movie at the US weekend box office this week. And 21's success is definitely because Kevin Spacey is in it, not because loads of attractive young folk hint at scenes of graphic rumpy-pumpy in the trailer. No sirree.
