Britt Reid (Seth Rogen) is a slacker by day, party animal by night... until he finds a serious career that's seriously cool: crime-fighting action hero. As the Green Hornet, he teams up with gadget wiz and martial arts master Kato (Jay Chou) to take down LA's underworld. Even Britt's assistant Lenore (Cameron Diaz), doesn't suspect this mismatched pair is the masked duo busting the city's toughest thugs led by Chudnofsky (Christoph Waltz). With style, swagger and an arsenal of awesome gear, the Green Hornet and Kato are doing justice their way, making every mission a mix of over-the-top action and outrageous comedy.
