I certainly don't get a sense that these guys think they are "above" non-actors, or that they condescend to them. They certainly treat people that are not in show business probably a little differently than those that are in, but so do people in all industries, entertainment or otherwise. Insurance people relate to other insurance people one way, and everyone else a little differently. Same thing with contractors, or musicians, or people in the food industry, or anything else. It's not a "superior/inferior" thing, at least not intrinsically.
Just my two cents.
Although Bateman does come across as a little pretentious even to the other two, with his dietary habits, and Arnett for one certainly does his part to put him in his place.
Arnett is great! when he was ribbing Bateman about being asked if and when he'd shower again......dude lost it.
I guess there are times when maybe I read too much into how they're going about the conversation.....there have been instances where (to me) they've come across as if they believe they're curing cancer or something in being actors and having to deal with their work schedules and methods.
If it matters to you, I get what you're saying. It's subtle, but I believe it's there. "Superiority" isn't the right word, exactly, but an air that they somehow recognize they're not like other people. My daughter, through her schooling, has had the opportunity to meet and hang out with several celebrities (because of their kids) including Titus Welliver and Eric Bazilian, among others, and doesn't agree it's "superior" either, but she does say it's different. I think it's like anything else; you get accustomed to your surroundings. Many of these actors are told over and over how great they are, how creative they are, "how amazing they are!", and it sticks. Bruce Springsteen talked about this, I think, in his interview with Howard Stern a couple months ago. Even if the actor themself isn't pretentious, the entire set up IS; you only need to watch one awards show to see that.
Sidebar, I used to live in Glastonbury, Connecticut. Several celebrities live there, including Christine Baranski. One time I was getting breakfast and Chris Lemmon walked in with his wife/girlfriend/partner/whatever. They were catty-corner to me so I could basically hear a lot of their conversation with the waiter. He ordered an omelet, and for all the instructions he gave, I'm surprised the cook didn't come out and say "you want to cook it yourself?" I don't remember all of them, but I do know it started with just egg whites, and there were precise instructions as to how much "browning" there could be on the edges.
