My vote would also go to Catherine McCormack. Mothma should be a politician who suspects that Palpatine isn't what he seems. I think Palpatine will try to kill her but she escapes and starts the Rebellion against the Empire in Ep3. I don't think she should have that big a role. Maybe the same screen time as Boss Nass had in TPM.
Oh, I totally agree with that, Palpatine sets it all up on Mandalore and has C'Baoth and other Dark Jedi guard it. Once the senate learns of this however and the war starts, big eruptions go on in the senate. Palpatine is obviously for it, as he plans on building the military force that starts his Empire through clones. Perhaps senators like Bail and Mothma forsee this and blast Palpatine for it in the senate.
sorry xizor, i never saw this post. i'll go delete mine above since it was along these same lines. i think it would be cool if Caroline Blakiston returned to the role. here is what i wrote above:
"where is mon motha? is she in the senate during E I?
i hope she has some kind of role in II and III. she is far too important to the rise of the rebellion to leave out. the time she got in VI was not enough if you asked me. anyway, i hope she is appearing in the next two. who do you think should play her character? it would be nice if they could cast Caroline Blakiston to return to the role as they have done with Ian McDiarmid (but they would have to make her look a bit
younger)."
