There is a certain kind of respect for authenticity today that there wasn't back in the days when they did 'Cleopatra ' where everything looked like a giant motel. People want to have it be authentic in the look and authentic in the way people behave.
It didn't matter what you look like. You don't have to get up at 5:30 in the morning and there's a lot to be said for that. Corpse Bride can just play all my parts from now on and I'll just do the voice.
