E! is reporting that Joss Whedon (Buffy the Vampire Slayer) is presently developing a documentary feature about the San Diego Comic-Con with Supersize Me director Morgan Spurlock.

The film is going to be cast with convention-going superfans.

"They want to follow people for about three months leading up to this year's Comic-Con," a source close to the project said. "And then they want to film them there. They're looking at all types of people."
