Okay, well, maybe he was joking, but it's not like Shia LaBeouf hasn't insulted some of his movies in the past (ahem, Indiana Jones and the Kingdom of the Crystal Skull).
When Jimmy Kimmel brought up a past interview where Shia "was telling us the movie you were promoting is crap," Shia told the talk show host, "Well, nothing's changed! It's still…"
LOLz! Oh dear, Shia. Nothing like sticking your foot in your mouth once again. We're sure your "friend" Michael Bay and Transformers director will just love that.
