Costar Mia Wasikowska confirmed the drunken behavior, which is labeled as “method acting.” LaBeouf even admitted to it, saying, “Mia was ready to walk away from the movie. I was really pretty aggressive about it, and not in any kind of weird, strange way, but I don’t think she had ever experienced anything like that.”
It’s extra strange because LaBeouf’s character isn’t a heavy drinker. He just pushes the moonshine.
