Drake Bell

Nickelodeon has green-lit a live-action TV-movie adaptation of its hit animated series The Fairly Oddparents, TVGuide.com has learned exclusively.

The movie, titled A Fairly Odd Movie: Grow Up Timmy Turner!, will mix live action with CG animation and will follow a now-23-year-old Timmy, to be played by Nickelodeon vet Drake Bell (Drake & Josh). Seinfeld's Jason Alexander and Curb Your Enthusiasm's Cheryl Hines play Timmy's godparents Cosmo and Wanda.

"It's so much fun to see our animated characters come to life," Marjorie Cohn, Nickelodeon's programming president, said in a statement. "And who better to bring grown up Timmy Turner to life than Drake Bell, who himself grew up on our air and still remains one of our most popular Nick stars ever."

The animated series focused on 10-year-old Timmy's refusal to grow up, so he could keep his fairy godparents. In the movie, an older Timmy is still in the fifth grade and living at home, but all that changes when he begins to have feelings for Tootie (Victorious' Daniella Monet), a nerdy girl who has grown into a beautiful woman and returned to town. Timmy must make a choice between his godparents or growing up and being in love.

"I think fans of the series will love seeing the characters in this new way," creator and executive producer Butch Hartman said. "Our mix of live-action and special effects animation will make them look 'hyper-real' and our goal is to make this movie as visually exciting as it will be funny."

Steven Weber (Wings, Studio 60 on the Sunset Strip) also stars as a larger-than-life oil tycoon, who turns his attention to capturing Timmy's fairies and using their power to fuel his maniacal ambition.

The movie is set to debut on Nickelodeon in 2011.
