Kwon Sang Woo will not be portraying The Green Hornet's sidekick, Kato. Jay Chou beat him to it.

When Hong Kong star Stephen Chow dropped out of Michel Gondry’s The Green Hornet, the race was on to find a new Kato. Hallyu heartthrob Kwon Sang Woo (33) was one of the Asian stars vying for the plump role.
However, the new father’s Hollywood dream is crushed with the announcement that Taiwanese star Jay Chou has landed the role of Kato.
Chou (30), who is a talented actor and musician, will be joining Seth Rogen, Cameron Diaz and Nicolas Cage for the production.
Kato was famously portrayed by Bruce Lee in the original television series.
