Rainn Wilson, in the Spirit

Get ready to see a whole lot more of Rainn Wilson than you ever would have imagined.

The costar of NBC’s “The Office” says he dropped trou for a few comedy sketches he taped as host of the Spirit Awards, the Oscars of independent film.

“When I signed up I said, ‘I’m not a stand-up comedian. I’m happy to tell jokes and stuff but it’s not really what I do,’ ” Wilson said in an interview Wednesday.

“And you know, they were like, ‘Great, let’s film some stuff and make it close to what you did when you hosted “Saturday Night Live.” ’ That’s kind of what we’re aiming for -- just funny comedy stuff. I assure you, I make an [idiot] of myself.”

The Spirit Awards, sponsored by Film Independent, air Feb. 23 on IFC. The show will be broadcast live, uncut and without commercials.
