Previously titled Lamb of God, the film centres on a young woman who moves to Las Vegas to explore her wild side after losing faith in God following a plane crash, Deadline reports.
Julianne Hough will portray the girl, while Russell Brand will play a bartender who guides her through her crisis of faith.
The two were first reported to be in contention for the roles in August.
Meanwhile, Hunter will play the mother of Hough's character.
