"Kristen Stewart plays Marylou, and she's really the female lead of the film. She's the only woman that goes on the journey with the guys and is sassy and crazy in her own way. One of the great things that we had, before the film was shot, was Marylou's actual daughter, Anne Marie, was part of production. She and Kristen spent a lot of time together talking about her mom and stuff like that."
