From a pure "hotness" perspective, I believe the best I ever saw Belladonna look was in Pirates II.
Belladonna cleaned up real well. I don't much care for the shaved head and Earth Mother thing she has going. She had a tendency to look like she was madeup by someone who was playing a joke on her. When she had her makeup done nicely, she's really pretty. The girl next door who does double anal fisting.
