Caroline, from Caroline, or Change. She may seem one noted, but she is definately not. There is a level of commitment, and intense focus on not only singing those songs, but also to make sure the character is slowly building up, to make her explosions really explode, then back down again.. to EXPLOSION.
Tonya Pinkins was Caroline, so complex, but clear at the same time. It was an awe-inspring journey that I took with her.
Sally Bowles. There is so much subtext to her flighty appearance. It's easy to play her as blithe, carefree, ignorant, but the really good actresses play her with a bithe, carefree, ignorant surface and a festering, decaying, highly aware self underneath, and it's a beautiful contrast, and a much more interesting show.
Sweeney. He's not just angry. That's like saying Hamlet is angry. Sweeney is a complex human, with SO many levels, and it takes a subtle human to show us bits and pieces of his character through words here, and words there.
Torvald/Nora, A Doll's house. To very interesting characters, that can easily fall into tropes of oppressive man, and independent caged bird, because they are both so much more than that.. Neither are so cognant of their social situation, but they are rather living in it, going through the normal motions of society, but one just figures out that there's something wrong with the system sooner than the other. So, if done well, the play can be a lot more interesting than some productions make it out to seem.
Personally, I think I have too much bloom.
