the best way to cast Wonder Woman in my opinion would be with an undiscovered actress/new actress. Don't go the established route. Wonder Woman should be about the strength of the character herself, not about the actress playing her.
My current interest is due to straight up boredom. During college I worked at an antique bookstore that was on the same street as a comic book store and I found a good way to burn through boring afternoons would be to sit down with a stack of comics.
....it was a really boring job, I spent a LOT of $ on comics. Since then I've moved to strictly digital purchases which has been pretty sweet (yet, expensive).
As a kid, my interest was first sparked when I broke my elbow and while in the hospital my Dad bought me the trade of Star Wars Dark Empire. I must've read that thing 20 times through that summer and I still revisit it once a year.
