The movie, which had been titled Lamb of God, will start shooting later on this year with Mason Novick set to produce, according to The Hollywood Reporter.
The film centres on a young conservative religious woman, to be played by Hough if she takes the role, who loses her faith after a plane crash and decides to take a trip to Las Vegas but while there she rediscovers her faith.
Brand is set to play her companion who helps her to find herself again.
