joni as queen of hollywood

[Garret]

If you could cast Joni in any role from any movie, made or yet to be made,
what character would that be?? Lady Macbeth??  Forrestt Gumps mum?? the
mother superior in sound of music?one of the women in first wives club?
helena bonham carter's character in fight club? Mrs Robinson? Annie Hall?
what about Helen Mirren's character from the Madness of King George, Queen
CHarlotte? or even Galadriel in LOTR?
 and why?
Just something to think about:-)
