NBC has decided to expand the second season of Chuck from thirteen to twenty-two.

Word came out on Tuesday that, after seeing the first six episodes, NBC execs decided the show deserved a full season.

There appear to be big plans for the second season, as the show has a lot of guest appearances planned.

Jordana Brewster, John Larroquette, Michael Clarke Duncan, Tony Hale and Nicole Ritchie have all signed on for appearances.

Chuck returns on Sept 29th.
