I cast a few of Spider Man's rivals and I'll start with Mary Jane
Mary Jane has been one of the most difficult difficult women in marvel to cast so here is a list of actresses that might work
1.Kristen Dunst
2.Danneel Harris
3.Erica Durance
4.Jaime King
5.Kate Hudson
6.Alicia Witt
Rachel Nichols as Black Cat
Cripin Glover as Electro
-as I can recall you guys have been casting him as the Joker my pick is Electro.
Electro woud be the best role for him.
Denis Leary as HobGoblin
Topher Grace as Venom
I like the idea of venom being like an evil twin brother to Spider Man.T don't know about you guys but i loved venom's costume on film you can really see where venom obtained the webbing from and the spider emblem on his chest plus knowledge of Peter Parker.
Jake Gyllenhaal as Carnage
hey guys i hope you don't mind the labels on the images :D.
