And he's just getting started!
Get the rundown (below):
But this just may cross some lines. The lines on his face. With a knife.
"We were in make-up and they were putting cuts on Shia and I said, 'Yeah, yeah, it looks good.' And Shia was like, 'No, it doesn't look real.'
Then he walks out into the hallway and says, 'Hey man, wanna see something fun? Check this out…' and he takes out a knife and cuts his face. And for the whole movie he kept opening these cuts on his face. That's all real."
Whoa, WTF, Shia?
This is the most extreme thing the actor has done since… OK, we guess this isn't nearly the most extreme thing he's done.
Is Shia keeping it real for the movies? Or has he stepped away from reality?
