She took inspiration from another darkly iconic character for the role of Prudence.
Do Prudence's sphinx-like mannerisms and smooth, syrupy, sort-of British lilt remind you of anyone? They should. Gabrielle revealed to W that she transformed herself into Prudence by looking to the late Eartha Kitt, whose own distinctive speaking style brought life to her legendary portrayal of Catwoman on TV in the 1960s.
"The accent just kind of came to me," Gabrielle said in a recent interview. "But as far as her mannerisms, I'm a really big fan of Eartha Kitt; that was a big inspiration for me. Eartha was such a powerful woman, just as herself, and the way that she'd sway and move. She was the original Catwoman, but she was literally like a cat. She was a panther in the form of a human being."
