Comic-Con — the annual pop cultural extravaganza that brings a host of movie and TV stars, authors and, yes, genuine comic artists to San Diego each year — long ago became a magnet for celebrities. .

As such, the usual well-known Comic-Con suspects — your Stan Lees and Kevin Smiths — will descend on the South California city starts July 21, as will famous people that one does not typically associate with Comic-Con’s nerd herds — Justin Timberlake , Ryan Gosling , Carey Mulligan, Bradley Cooper , Colin Farrell, Charlize Theron and Stephen Soderbergh, to name a few. (View the gallery above to see photos of even more.)

And then there are the stars with previously established geek cred — the geekarati, if you will — who will promote new projects at the Con but are already revered for their involvement in past pop cultural phenomena.

Which of those phenomena boasts the most star power at this year’s event? I chose four key geek-friendly movies and/or TV shows and did a completely unscientific, admittedly silly data comparison in the hope of finding an answer.

Note: all superhero-related films and shows have been omitted; at a convention where some fans need a valium to stay calm while discussing the next Spider-Man movie, that seemed like the only way to keep this pseudo-competition fair.

Technically “Trek” wins, though if I had included “Robot Chicken,” whose voice talent has included at least half of the Comic-Con geekarati, it would easily triumph.
