The hilariously intense, raspy-voiced Arnett is probably best known for (or at least, I first noticed him in) his role as George "Gob" Bluth, III. That's "Gob" pronounced "Job", as in biblically-speaking. When asked about the experience of working on Arrested Development, he said of the pilot that it was "the best I ever read--and I hope that insults every other pilot I worked on."
His style is over the top comedy with a straight face, and there's something about him that totally cracks me up. And for some reason, I find him completely sexy, even when he's at his most ridiculous.
He's hysterical as Amy Poehler's figure skating partner/brother in Blades of Glory; he's appeared as a gay executive with a letch for Page Kenneth on 30 Rock. IMDB lists multiple upcoming performances to look forward to, most notably the voice of super-car K.I.T.T on a new TV remake of Knight Rider. Here's hoping The Hoff will at least be making a cameo!
Some fun Will Arnett trivia, courtesy of IMDB:
Speaks fluent French.
Attended French-speaking schools in Toronto.
Does voice-over work for GMC trucks and Lamasil tablets.
See, we're perfect for each other! I speak French! I...haven't been to Toronto, but it's on my list! And I don't have nail fungus, but if I did, I'm sure Lamisil would clear it right up! Too bad he's married to Amy Poehler in real life. And Penelope Ann Miller before her, but we won't get into that. He traded up, that's all we need to say.
