Sorry, I'm back so late. And even more sorry for telling bullsh..
I'm so nervous that GL might do changes even to the SE now that I was buffled wwhen I read Ian mcDiarmids name. To stay to the truth. I was absolutely sure that the emperor in ROTJ was played by someone else and that Ians first appearance in SW was in TPM.
I apologize. and I apologize to Mr Lukas, too. (If only for this one thing)
