Maggie Q cast in 'Priest'

Joins adaptation starring Paul Bettany, Cam Gigandet

Maggie Q is joining Paul Bettany and Cam Gigandet in "Priest," a post-apocalyptic horror project that Scott Stewart is directing for Screen Gems.

Adapted by Cory Goodman from a TokyoPop comic, "Priest" is set in a world ravaged by war between man and vampires and follows a warrior priest (Bettany) who teams with a sheriff (Gigandet) to track down a murderous band of vampires who have kidnapped his niece.

Q, an Asian action star who toplined "Mission: Impossible III" and "Live Free or Die Hard," will play a priestess -- a vampire hunter as tough as the priests -- who also joins Bettany.

She is repped by CAA and Echelon Talent Management.
