Chuck is an American action comedy spy drama television series created by Josh Schwartz and Chris Fedak. The series is about an "average computer-whiz-next-door" named Chuck Bartowski, played by Zachary Levi, who receives an encoded email from an old college friend now working for the CIA. The message embeds the only remaining copy of a software program containing the United States' greatest spy secrets into Chuck's brain, leading the CIA and the NSA to assign him handlers and use him on top-secret missions. Produced by Fake Empire, Wonderland Sound and Vision, and Warner Bros. Television, the series premiered on September 24, 2007, on NBC, airing on Monday nights at 8:00 p.m./7:00 p.m. Central. The opening theme song is a wordless edit of "Short Skirt/Long Jacket" by the American rock band Cake.
