Jason Momoa (“Game of Thrones”) and Merritt Patterson are joining Lucas Till in werewolf thriller “Wolves,” with David Hayter helming from his own script in his feature directing debut.

Copperheart Entertainment, French financier-sales agent TF1 Intl. and Telefilm Canada will co-finance “Wolves,” set to shoot in Toronto this fall. Copperheart’s Steve Hoban is producing with Benedict Carver, Steven Paul and Hartley Gorenstein exec producing.

Entertainment One has acquired Canadian rights to the film. The producers will handle sales rights in the U.S., the U.K. and Benelux while TF1 Intl. will handle the rest of the world.

Till will portray an 18-year-old who’s forced to hit the road after the death of his parents and finds his way to an isolated town to hunt down the truth of his ancestry — giving rise to the question of who’s hunting whom. Momoa will portray the villain in the town.

Igor Studios’ Dave Elsey is designing the original creatures for “Wolves.” He created “Beast” for “X-Men: First Class,” for which he won a Saturn Award.

Momoa toplined “Conan the Barbarian” and just wrapped on “Road to Paloma,” a film which he co-wrote, stars and directs. He’ll be seen next in “Bullet to the Head.”

Patterson’s credits include “Radio Rebel” and “The Hole.”

Momoa is repped by APA and Bill Sobel at Edelstein, Laird and Sobel.
