I'm not buying suggestions for Ursula. Whereas all those actresses are fabulous character actresses, let's not forget that Ursula goes through a transformation. Emily's really the only one *classically* BEAUTIFUL enough to pull it off. She's incredibly versatile. I honestly can't think of another 'name' that would be more suited for the role. Putting the bias factor aside -- I honestly think that's true.
