One, Two, Three : I guess what Coens are trying to say is…

...how wide is the chasm between the real world and the screen world, for most part how spineless and puppet like are the "brave" actors are in real life. That acting someone else other than yourself does not make you grow as an individual, that acting is a grind and "being" a star is a self-delusion.

Well said.

The only real stars are out in the Universe. The rest are all space cases trying to get there.
