'Chuck': Olivia Munn spies on premiere

When "Chuck" meets G4's "Attack of the Show," nerd-vana will be achieved.

Olivia Munn will guest star as a CIA agent on the fourth season premiere of "Chuck," reports Entertainment Weekly.

She'll play a spy who has it all -- looks, brains and ability -- and thus instructs Chuck (Zachary Levi) and Morgan (Joshua Gomez) how it's done. We're fairly certain that she won't emerge from her interaction unscathed though.

She joins "Rocky" villain Dolph Lundgren, who will also poke his head in for the premiere.

Munn, who's co-hosted "ATOS" with Kevin Pereira since 2006, has earned fanboy love for her willingness to do almost anything for a laugh, look silly and play to the show's male demo.

She's no stranger to Comic-Con, having visited dressed as Princess Leia before, and will appear this year to co-host G4's convention coverage in San Diego.

Munn has also landed on an NBC sitcom, "Perfect Couples."

"Chuck" Season 4 kicks off on Monday, Sept. 20.
