I know its meant to be a different continuity and everything, but I just look at that and think "what's the point?" Seriously, is Lucy Lawless Wonder Woman because her voice acting suits the part, or because she's well-known as Xena?
According to Bruce Timm, its the former. They needed someone who was able to project a strong presence/voice, and Lucy Lawless' accent change when she played Xena was ideal to be casted.
