Has way too big of an ego

It would be one thing if he had acting chops to back it up, but he is a pretty bad actor and seems very arrogant. I don't care for the Fast and Furious films, but his behavior on the latest entry was childish and embarrassing. Refusing to do a scene that was written in the script, because it would make your character seem too weak, refusing to coordinate with fight choreographers until the film makers made sure that you and Vin Diesel had an equal amount of times you could be hit or fall down, and finally posting a nasty public message about a fellow actor who you had problems with for everyone to read when you should have had a private meeting to clear up your problems in a civil manner.
