Seth Rogen, the star of Knocked Up and writer of Superbad, is hard at work writing the script for the Green Hornet movie. Rogen is again writing it with his partner Evan Goldberg (Both wrote the script for Superbad). This time around Rogen will also star in the movie as the Green Hornet. As for the role of Kato, Rogen is eyeing Stephen Chow. He said that based on the way the script is developing, they will need a guy who can do martial arts but also maintain a great sense of humor. Chow is the perfect fit for that description.
Word of warning to Rogen though. He should be prepared to get upstaged by the enormously talented Chow.
