People entering the convention hall during Comic-Con 2010 in San Diego, CA.

Comic-Con, the veritable mecca of sci-fi freaks and fantasy geeks. What was once a small get-together for comic book-philes has become a pop culture juggernaut. Even Johnny Depp has shown up to promote his work.

Now Morgan Spurlock, the documentarian who turned a critical eye to fast food in "Super Size Me" and to mega movie marketing and product placement in "The Greatest Movie Ever Sold."

His look at Comic-Con is more affectionate than critical, embracing the earnestness of five different pilgrims to the 2010 convention in San Diego, among them a rare comic book dealer and an amateur costume and makeup artist using Comic-Con’s costume play competition to get the attention of filmmakers and producers.

WEIGH IN:

If you’ve been to Comic-Con – or just longed to go – have a listen and give a call. Has it become a casting call for big ideas in the sci-fi and fantasy world?
