Summer Glau (River Tam in Firefly etc.) is going to be the voice of Supergirl in an animated film coming soon:

I'm not to impressed by the artistry. Superman looks kind of gaunt, so does Batman. And, of course, they both have really large chins, lol. I always have to laugh at that with Superman cartoons.
