Charlize Theron got drunk in an effort to research playing a boozy woman in new film Young Adult.
The actress portrays a struggling author who returns to her hometown to break up her high school boyfriend's marriage, and her character is inebriated for much of the film.
So the Monster star chose to study drunken behaviour and discovered why it's so hard to pretend to be over the limit.
She says, "One night I actually went and got drunk to figure out why it's so hard to play drunk. It is because when you are drunk all you're trying to do is not be drunk. Actors, when they play drunk, they're like, 'Oh, I'm so drunk,' but nobody does that."
