The Green Hornet was always more of a pulp hero than a superhero. We need more pulp hero movies. Where the hell is Doc Savage? There's enough superhero movies made and in the works as it is.
Seth Rogen will probably be okay. GH was never the ass-kicker of the outfit, he was the investigator. Kato did the footwork and fistwork and driving. They cruised in a high-tech limo called Black Beauty.
The original show was never meant to be super-serious, so Rogen will fit in, and Stephen Chow is perfect to play Kato and direct. Kung-Fu hustle rocked!
