This sounds consistent with what people who've worked with him have said. If he's known to be self-centered and a dikkhead then it's unsurprising that he'd say things like this.
I said it the first time around, if he's known to be an abrasive person, he's going to be found guilty in the court of public opinion. It's not like we're talking about someone who is known for being fun to work with like Denzel Washington. He thinks he's already a big deal and is walking around acting like he's the lead in the movies he's in and people are there to see him. You won't get far in Hollywood with that mind set.
