Zachary Levi sings great in 'Tangled'. Why no musical 'Chuck'?

"Chuck" star Zachary Levi was shocked when he got the role of Flynn Rider in Disney's new animated 3D musical film, "Tangled."

Being a self-confessed Dis-Nerd, he begged his agent to get him an audition but he fully expected the juicy role to go to an A-list actor. So now that he's proven he can sing so amazingly well, when's the musical episode of "Chuck?"

"I don't know if that's a good idea," he admitted at the "Tangled" junket on Sunday (Oct 26) in Disneyland. "Shows like "Buffy" and "Scrubs" all have the premise that can support that. But while "Chuck" can be very funny and tongue-in-cheek, I feel like it would interfere with the integrity of the show. Then it would be the Muppets episode."
