Also for a Riddler character, it needs to be Robin Williams. He is still funny enough to pull out some good evil laughs, but also old enough to get really demented and creepy scary.
OK, this may be a little out there but doesn't former gymnast Dominique Dawes do some acting? It would be cool to see someone that can actually do alot of the acrobatic stunts and also has a build that you could beleive they could do those stunts.
Another girl that just looks like a villain is Jillian from Biggest Loser, she's scary!
Maybe, just maybe.......Tilda Swinton?
Just throwing that one out there
She could be a villain. Not a good girl that sometimes is very, very naughty and needs a spankin'.
Just trying to feel you guys out since I honestly feel Beckinsale would be contacted early in the search for this role if they were to even incorporate Catwoman into the franchise.
Oh and by the way Tilda Swinton was meant to be a joke, no I do not want to see her in latex but thanks for the mental image.
For the Riddler, I keep picturing Rainn Wilson.
Heres the list I can think of for potential villains
I can't think of any others
Mr Freeze and the clay dude don't seem to fit the current movie trend as previously pointed out.
I thought much of the beauty of the movie was the "realism" of the thing. It did things like calling attention to the fact that he does have to carry all his gadgets on his belt and he just didn't have an item for every situation. Also, the way the development of good to evil happened with two face. There are others but I can't think of them right now. But I just don't see the "fantasy" kind of villains fitting in.
