Zachary Levi joins 'Chipmunks' sequel

'Chuck' star to tangle with tiny threesome

Alvin, Simon, Theodore and ... Chuck?

Zachary Levi, star of the NBC action comedy series "Chuck," has been cast opposite the computer-generated singing rodents of "Alvin and the Chipmunks: The Squeakquel."

Betty Thomas is directing the follow-up to Fox 2000 and Regency's 2007 hit "Alvin and the Chipmunks," which grossed $217 million in North America. Ross Bagdasarian Jr. and Janice Karman are producing, Karen Rosenfelt is executive producing, and Erin Siminoff is overseeing for Fox 2000.

Levi will play the cousin of Jason Lee's character and gets tangled up with the tiny animated threesome. Justin Long, Matthew Gray Gubler and Jesse McCartney again will provide the chipmunks' voices.

Also new to the franchise will be the Chipmunks' rivals, the Chipettes -- Brittany, Jeanette and Eleanor -- who were introduced in the 1980s animated TV series.

Levi, repped by Endeavor and Hyler Management, also has appeared in "Big Momma's House 2" and "Shades of Ray."
