Academy Award winning writer Diablo Cody will make her directing debut on her own script Lamb of God. Her longtime collaborator Mason Novick will produce. It seems that the movie is being fast tracked since casting is beginning right away.
Here's the description off the Deadline site:
The comedy follows a young conservative religious woman who loses her faith after a plane crash. She decides to go to Vegas and live the life of a sinner, and somehow finds her faith along the way.
