 Lisa A. Morrison was forced to leave the production to serve a tour  of duty in Iraq for the U.S. Army before she completed all of her  scenes for the film. The remaining scene that Lisa was not able to  appear in was a hallucinogenic nightmare sequence (scene 33) with  the character of Ashley Lomack (Emily Haack) that had to be  completely rewritten from scratch to involve the Mikki Lomack  character without having Lisa on set.
