Will Ferrell really only has one gimmick. It’s the “Look! I’m middle aged and am doing something SO crazy!” gimmick. Likewise, “Blades of Glory” only really has one joke: “Men figure skating together! That is SO silly!” This joke is stretched into a 93 minute movie.

And, fortunately for “Blades of Glory,” it somehow works.

“Blades of Glory” features two other actors who only really have one thing going for them: “Arrested Development”’s Will Arnett and Jon “I Will Forever Be Napoleon” Heder.

Arnett really only plays one character in anything he acts in. Fortunately enough, this character happens to be hilarious. Arnett could say anything at all, raise his eyebrow and slap a dramatic tone on it and still be funny. This skill earned him some of the funniest lines in “Blades of Glory.”

Heder, still clinging to the occasional Napoleonism, seems to have finally found a different movie that works for him. After crashing and burning as a sad, real world Napoleon Dynamite figure in “School for Scoundrels,” Heder’s character in “Blades of Glory” manages to take the “Napoleon Dynamite” quirks, keep them funny, but mold them into a separate character (mostly separate, anyway).

Heder’s character–effeminate, sensitive figure skating champ Jimmy MacElroy–clashes with the sex-addicted, hyper-masculine Chazz (Ferrell) to the point where their antics get the two banned for life from their division. After some time out of the limelight, Jimmy and Chazz are brought back together upon realizing that the only way they can make it to the top again is to enter in the double’s division – together. Hilarity ensues.

“Blades of Glory” basically only really works for one reason – competitive men’s figure skating really IS that funny. It’s a silly idea, and when you play up the silliness, everyone can appreciate it. The typical Will Ferrell absurdity falls into place naturally. This places “Blades of Glory” above “Anchorman” but still beneath “Talladega Nights.” Not everything can be as funny as NASCAR.

Ultimately, “Blades of Glory” is nothing amazing. But it is funny, and that’s what it’s supposed to be.
