What we did not have, at the time, was this video, shot by the folks at Screen Junkies. The website famous for all those "Honest Trailers" actually filmed inside the art project. After waiting in line for four hours (something we, too, contemplated), Hal Rudnick, host of The Screen Junkies Show, entered the exhibit and sat down with the actor, recording everything with a head-mounted camera. Then, he removed the famous "I'm Not Famous Anymore" bag from LaBeouf's head.
As you'll see from the video below, it gets more funny and awkward from there. Rudnick himself proclaims that he successfully "annoyed Shia LeBeouf for several minutes." Say what you will about LaBeouf, but it's impressive how he maintains his composure. He may (or may not) be a hack, but this video proves that LaBeouf is at least a committed hack. (Screen Junkies)
