In an article at The Los Angeles Times, the author writes that there’s a possibility that Adam Sandler will appear in Sony’s The Green Hornet opposite Seth Rogen:
I also heard a random rumor about the ‘Hornet’ film: Two different people in the industry told me that Adam Sandler has a brief but key role in the movie as a certain surprise superhero…I heard which one, too, but I don’t want to ruin it. Sandler and Rogen have another project together as well.
The studio has yet to announce a new director after Stephen Chow dropped out (he’s still expected to play Kato), but it is still targeting a June 25, 2010 release.
