Chuck Bartowski, our favorite TV nerd. Actually, don't let the nerd tag fool ya … Chuck, as played by all-kinds-of-yummy actor Zachary Levi, is a nerd, but a very adorkable nerd. In fact, he's the leader of the Nerd Herd, the Geek Squad-ish computer experts who work at the fictitious Buy More superstore. But, through a fluke that later turned out to not be an accident at all, Chuck's big brain was filled with a computer download of the U.S. government's top secret spy info, meaning Chuck had to be recruited as an undercover spy himself. That has led to some dangerous – and hilarious – missions for the fake 007, as well as a crush on his beautiful spy handler, Sarah. He's also got a nerdy sidekick/BFF, Morgan, who's good for more than a few laughs; some quirky Buy More co-workers; and a sweet sister who's engaged to a doctor who's so smart, handsome and nice that the gang affectionately refers to him as Captain Awesome.
