Emma Watson as Supergirl!
Looks wise its not a bad idea and she's definitely a better actress than Laura Vandervoot (don't think I spelled that right). But unfortunately I think unless the film was made after about 10 years or so too many people would still associate her visually with Hermione Granger and by than she's not exactly a girl anymore. That's the problem with growing up through a very successful franchise, the world places you into one image. That's always been the big fear of people playing characters like Superman and Batman. But its not a horrible idea.
Definitely no for Daniel Radcliffe being Superboy.
It's not that I think she'd be terrible, I just think you could find someone better.
Although if they were going for a younger (seeming) portrayal of Supergirl with a wholesome bent, then I think it would work. Sort of a Supergirl: Cosmic Adventures (although certainly not "in the 8th grade").
.....What are you Ewwing about i simply meant that since the skirt has no pockets she'll have to put down the wand and it won't be like Herminie playing supergirl it will be like a good actor playing her....what do you have a dirty mind or something I tried to make meaning as obvious as possible :)
