if you look at Empire of Dreams and the other supplemental features on disc 4, I never realised what an unhappy miserable bastard Lucas was during the filming of the original trilogy, the way he discusses all the production issues and studio issues, it's a wonder he didn't put a gun to his head, It didn't seem like anyone on set liked him, his only method of directing seems to be ' Can you do it again faster and more intense!' and the cast don't seem to have a lot of love for him either, sure they're happy for the parts they had in the saga, but I doubt you'd find anyone who would jump at the chance to work for Lucas again.
