I was going to add this to one of the various Palpy threads, but they all have just rumors from the set. This is actually news direct from Ian himself what's in store for the character. So maybe some of what we heard could be true. The report is from ComingSoon.Net.
MTFBWY and HH!!Ian McDiarmid on Star Wars: Episode III!
Source: Teletext Thursday, October 23, 2003
Teletext spoke with Ian McDiarmid, who plays Chancellor Palpatine in Star Wars: Episode III. He says his character will be featured in "action-packed scenes" for the first time in the third prequel.
"You'd imagine that my character has been rather deskbound in the past but this time he will get to take part in the action," says McDiarmid. "I can't give the story away as George Lucas would kill me but I have been engaged in far more physical activities than any of the other films."
"I have found myself sliding down chutes at speed and landing on heaps of rubber, it's been a completely new experience for me. I haven't had to go down the gym to get fit for the scenes but I did need a few rehearsals to get up to speed."
"Most of my scenes have been with Anakin Skywalker [Hayden Christensen] who eventually becomes Darth Vader."
He added that "There's a lot of anticipation about the movie and I think it will be worth the wait."
