Amy Adams and Jason Segel gave theater owners an early look at their new Muppet movie yesterday in Las Vegas at CinemaCon. The costars had a few laughs as they chatted about the shared childhood love of Jim Henson's puppets that inspired their work on the project. Jason and Amy wrapped up shooting with Kermit and company recently while Amy was in the middle of her busy award season. Their film also features cameos from the likes of Jack Black and Emily Blunt, as well as some surprise stars that Jason says he hopes to keep secret until when the movie hits theaters on Nov. 23. Beyond the Muppets, Amy will get the chance to revive another classic character on screen soon since she just signed on to play Lois Lane in the next Superman movie.
