Vince Vaughn on his 'Freaky' new gender swap role

Vince Vaughn's latest role skewers the body swap movie genre - literally.

In "Freaky," Vaughn plays a serial killer who just so happens to switch bodies with a high school girl, Millie (Kathryn Newton).

Of course, in addition to the usual hijinks, Millie finds herself stuck inside the body of a muderous psychopath.

"I don't like being a serial killer," Newton joked to Yahoo Entertainment. "I don't even know how to cook in the kitchen so I don't know what I'd do with a whole body."

Vaughn added of the dual performance, "You're building two characters and then you have someone else and all their great ideas and you kind of construct it together."
