Things I'd bring with me when going on the lamb: cash, a fake ID, and a fast running car. Things I'd leave at home: an elderly relative. In Tammy, Melissa McCarthy plays a woman who becomes a fugitive from the law with her grandmother--played by Susan Sarandon--headed for Niagra Falls. Hilarity obliviously ensues.
McCarthy also makes her screenwriting debut with the film--co-written by her husband Ben Falcone.
