The movie is about a group of inmates at an insane asylum who try to escape, and the cast all completed arduous training ahead of shooting.Vanessa got so fit she could lift 180lbs. by the end and says the experience had a profound effect on her.It was amazing how [the diet] really kept us going, we were on our A-game, We were kind of unstoppable she mused.Jena also felt the effects of the preparation. Although she doesnt know if she could keep up the strenuous program in the long term, shes glad shes experienced it as it showed her just what shes capable of.I look back on it fondly, I miss it, it would be incredible if I could do it again absolutely, but its not like Im like, Oh my life is horrible now Im not training for ten hours a day, because theres only so much your body can take, she told Collider.They were training us to be high performance athletes and that was our diet. It was totally trying to keep us clean and give us energy throughout the day. It was a really good education.The group bonded due to the pressure they were under. They all found the intense regime difficult to cope with, although they would meet up off set and tuck into dessert as a treat.One of the toughest things for the girls was not being able to drink fizzy beverages, so Jena took matters into her own hands when their need got too great.There was no soda on set but I did commandeer a golf cart and we went and stole sodas from CSI. It was super amazing, it was an unguarded ice cooler, she recalled. (C) Cover Media
