I can't think of any, but most of the original cast were inexperienced in everything when the first trilogy was made. She was however very experienced in general, but didn't have a name big enough to throw around against Lucas. This seems to fit his overall attitude in the OTL prequels of casting experienced actors (with a notable exception) rather than the amateurs he used for the original Star Wars.Did she ever do any action roles?
I always think of her as the Queen in Blackadder .
