Seth Rogen in homemade “Green Hornet” costume

Here’s our very first look at Seth Rogen dressed in the “Green Hornet” costume. We can’t tell if the photo is of Seth Rogen in costume or a stand-in or stunt double, but its looks like he’s been ripped straight from the old series.

Splash News has posted a video from the set of the masked vigilante adaptation which contains a brief glimpse at Green Hornet’s costume. It isn’t clear whether the man behind the costume is Seth Rogen or his stunt double.  Aside from exposing first look at the vigilante’s costume, the video also displays some on-set explosions. A peek at Kato in his crime-fighting costume is also available to view.

“The Green Hornet” cast also includes Jay Chou as Kato, Cameron Diaz as love interest Lenore “‘Casey” Case and Christoph Waltz as villain Chudnofsky and is directed by Michel Gondry. It will be released on December 22, 2010.
