You know what you're getting with a Will Ferrell movie – no real plot, long improvisation scenes and humour broad enough to drive a down – but the formula seems to work, since new Will Ferrell movie Blades Of Glory is top of the weekend box office.

But that's not to say that Blades Of Glory is just another Will Ferrell film like all the rest – Blades of Glory got the number one US weekend box office spot by being completely different to all the others. For instance, in Blades Of Glory Will Ferrell plays a stupid over-masculine American man who tries to make a professional comeback fraught with hilarious moments, while in Talladega Nights Will Ferrell played a stupid over-masculine American man who tried to make a professional comeback fraught with hilarious moments in a car. Big difference. Huge.

Blades Of Glory is the number one movie at the weekend box office, which isn't a bad turn-out for what seems to be a great big 90-minute-long gay joke about Will Ferrell touching Napoleon Dynamite's penis and grimacing. But that seems to be what the weekend box office wants, so we're guessing it won't be long before there's a flood of copycat movies about Jack Black touching Napoleon Dynamite's penis and grimacing, Tom Cruise touching Napoleon Dynamite's penis and grimacing and Sir Anthony Hopkins touching Napoleon Dynamite's penis and grimacing. Here's the US weekend box office top five…

1 - Blades Of Glory (By copying Dancing On Ice, Blades Of Glory has become the second most popular reality TV-related movie of all time, after that clip of Rebecca Loos wanking off a pig) $33,000,000

2 - Meet The Robinsons (A Disney movie starring Sugar Ray Robinson, Jim Robinson, Robinson Crusoe, Tony Robinson, Heath Robinson, Smokey Robinson and three jars of Robinson's marmalade. But not Anne Robinson, though, who pulled out due to schedule conflicts with her other movie, Meet The Angry Ginger Old Ladies) $25,056,000

3 - 300 (300 has managed to make history cool to young male audiences again, something that can't be said for the forthcoming follow-up to 300 – a big-budget, gore-filled comicbook version of the 1946 founding of the Vancouver City Savings Credit Union) $11,155,000 

4 - TMNT (TMNT's swift drop from last week's weekend box office number one spot means that the TMNT studio is now quickly reassessing its decision to make a brand new computer animated Chorlton And The Wheelies movie) $9,160,000

5 - Wild Hogs (Chances are this will be the last week that we get to write about Wild Hogs, and thus the last week that we'll be able to openly wonder why the hell William H Macy ever decided to make this movie in the first place) $8,389,000
