Shia took a shot at Transformers by saying, “I would just like to make movies about people now,” and “If I could give the money back and get all the credibility in the world that I’m seeking, I would do it tomorrow.” Well of course Shia didn’t mean a damn word of what he was spewing because he’s apparently on board for the fourth Transformers movie, and he’s demanded an $18 million salary as if the franchise should be grateful to have him. In an interesting twist and according to Star, Spielberg has apparently told Shia to stuff it.This has not been confirmed at all so don't read to much into but suffice it to say if Spielberg says no, its not going to happen. Long story short, nothing has changed. Thanks to Ben for the link.
Update: In a comment to RumorFix, the story has been denied by LaBeouf's representative, "The story is a complete fabrication. While Shia remains very close with the filmmakers/studio, he was never attached to the fourth installment (nor is he in negotiations at this time). Salary did not impact his decision." Thanks to Ray for the heads-up.
