Esquire interviews Cornish about why she chose to audition for the film Sucker Punch and the kind of training she did to prepare for the role.
[It’s] something really trippy like a concept film, where I’d have to really use my imagination and do crazy things. Mixed martial arts, fighting, swords, weapons, choreography, personal trainers. We add gun stuff at the end of the day. It was funny to want to do that kind of movie and then it just comes along.
