Dominic Monaghan ("Lost," "The Lord of the Rings" trilogy) has landed the lead role in Edna McCallion's psychological thriller Pet for MGM, says The Hollywood Reporter.
Monaghan will play Seth, a man who bumps into his old high school crush and quickly becomes obsessed with her. He takes her captive underneath the animal shelter where he works but soon suspects that his old flame is not who she seems to be.
Monaghan will also star with Ron Perlman in Glenn McQuaid's period zombie flick I Sell the Dead for Glass Eye Pix.
Pet, set to begin shooting in the next few months, is produced by Aaron Kaplan, Sean Perrone, Steven Schneider and Dan Katzman.
