"It was the bible that gave it , its R rating"
Actually, Chook might be on to something here. Maybe the movie makers contacted Watchtower asking for permission to use the NWT bible and Watchtower initially said no because they're afraid that JWs seeing the movie would be stumbled by it as it would indicate that the organization is partnering with Satan's world. After some back and forth negotiations Watchtower suggests that they can use the bible on one condition: That the movie be R rated. That way no JW would/should watch it and get stumbled. lol.
