Nathan Fillion is awesome (see Castle, Slither, Firefly and Serenity for proof). That’s why he’s starring in the fake trailer for Green Lantern.
It’s a mash-up of new stuff with Fillion, and pieces of Star Trek, Transformers, Matrix Revolutions and other sci-fi epics mixed in, as well as the less-than-epic Fantastic Four: Rise of the Silver Surfer. This is why Nathan Fillion is Hollywood’s most underrated actor. Because he has the man parts and brain to do stuff like this while making absolutely nothing to do it.
