Relativity Media, Archaia Entertainment, and Fandango have teamed up to find Apollo and Artemis for the graphic novel tie-in for Tarsem Singh’s fall epic “Immortals”.

Here’s how the contest works: Participants will share their reasons as to why they are the perfect candidate to become the Greek God Apollo or Goddess Artemis via the Facebook application form on the film’s official Facebook page. The top 10 entries (five women and five men) with the most “Likes” at the end of the contest period will be asked to submit “authentic” audition tapes for the roles to Relativity Media. Singh will select his two favorites (one man, one woman) and they will be crowned the winners.

The winners receive a bevy of prizes, including the grand prize in which the contest winners will be “immortalized” as graphic novel characters with the big reveal taking place during the Archaia panel at the 2011 Comic-Con International in a special photo-op ceremony. The winners will also receive an all-expenses-paid trip (including airfare and hotel accommodations) to San Diego to attend the Comic-Con. The winners also receive exclusive access to special “Immortals” events throughout the convention.

You can learn more about the contest at Fandango, the official “Immortals” website, the Facebook site linked to above, and the film’s official Twitter page.
