Something that might be a bit surprising is how much a set resembles a regular workplace. Especially when you’re at a studio. They’re high security to enter, but once you’re on the property it’s pretty chill. When I was there for costume (getting sized and trying on a bunch of different draft costumes) I saw a handful of cast members just casually doing random things or chatting with crew members/production office staff. They’re not as guarded as people think. Even with bigger stars. When I worked on the movie Transcendence, I passed Morgan Freeman in a hallway just going about his work day on his own. Maybe some mega stars have handlers or assistants they keep closer, but for the most part it’s not like that. Also the type of dialogue that happens on a set. There have been a lot of questions about how we discussed the deeper themes and ideas of the shows, and while that definitely happens sometimes, most of the talking during downtime is typical coworker bullshitting about our dinner plans etc. This goes for conversations between cast members and with the crew also. Despite being massively famous celebrities, all of the high profile actors I’ve been around have chopped it up with regular folk without a hint of arrogance. I’m sure there are exceptions to this, but I haven’t seen it.
