So I read on a couple sites that Sarah Michelle Gellar is going to be in the Dark Knight Returns as Harley Quinn. Of course none of this has been confirmed but it makes me really, really curious. I can't really see Harley fitting into the movie acting the same way she does in the cartoon. She's too bouncy. Maybe she'll just be Harleen Quinzel? I thought that Arkham Asylum is supposed to be in this one so it makes a little more sense. But a dark creepy Harley would be awesome. Either way I cannot wait for this movie. I wonder if Cillian Murphy is in it? I haven't really heard anything about him. Hmmm....
