10. Shia LaBeouf - Indiana Jones and the Kingdom of the Crystal Skull
No matter your opinion of Shia LaBeouf, and whether or not - in this case - he was right or not, it probably wasn't a good idea for the young and upcoming actor to say bad things about a Steven Spielberg movie. Which is exactly what happened in the aftermath of
Indiana Jones and the Kingdom of the Crystal Skull's release, when LaBeouf came out and said that Spielberg and company had "dropped the ball" with the third Indy sequel. Okay, so - technically - LaBeouf is just saying what we were all thinking anyway, but you have to consider his tact here. Steven Spielberg was the guy who took this kid from Nickelodeon brat and made him into a movie star via
Transformers. He owes everything to the guy. To go on record to say that your friend and mentor "dropped the ball" is pretty douchey. Harrison Ford, irked by Shia's behaviour, called him a "f*cking idiot." Cool.
