"but it's still ACTING."
Yes it is acting, but there's a certain realm of believability. For example, not everyone can play Glinda in Wicked because it takes a certain type which requires more than acting.
No, I totally disagree and I know this thread is specifically about 3PO, but maybe my education has given a certain amount of fearlessness and unbridled enthusiasm. I think if you are a good enough actor, with enough craft, that anyone can play any part.
Jenny is not a "Glinda" part - Glinda was written with a certain (horrible) actress in mind and crafted around her style. Jenny was written with Lenya in mind but it wasnt molded around her, she made an impression with that role but anyone can play Jenny if they just take the time to get into her skin.
Don't f*ck with me fellas. This ain't my first time at the rodeo.
