I wasn't sure if I'd seen her act anywhere until I checked out the filmography on her site. Turns out she's been in Smallville and Charmed, which I have on DVD, so I did a quick check to refresh my memory.
She's very hot, but I don't think she has a dominant enough screen presence for the role of Wonder Woman. She's not tall enough to be a "statuesque" beauty, and her voice is too soft and feminine.
I'd love to see her as a wicked ubergirl, like she was in her roles on Charmed and Smallville, though her powers on both of those were non-physical. But I just don't think she's right for the role of Wonder Woman.
