I have always thought that productions can't support "divas". I have no real experience with movie making, but I would imagine there is a ton of "waiting for X so Y can do Z". Not in a rude way, but I would imagine lots of people are expecting other people to be on point so they can do their job. In a certain sense I think that's kind of rad because it implies everyone is sort of working toward the common goal of making some movie magic. Being a "diva" may work in wrestling or certain types of live performances, but something like film production is far more structure and doesn't really want spontaneous change or dynamic alterations to the schedule.

On a purely personal level how can you be a "manly man™©®" be so fragrantly disrespectful of other people's time and talents. So many of these macho masculine self-help/guru types talk about being respectful and being a man and shit, and these is just actively un-manly. It's boyish. A boy would have this sort of mindset and behavior, not a man. It lacks honor, it diligence, it lacks consistency, it lacks all of the virtues people like Johnson espouse in their videos and "brand". You can't call yourself a man and be so self-centered.
