http://en.wikipedia.org/wiki/Spider-Man_3 Topher Grace...the really scrawny guy from That 70's Show is playing as Carnage.. wow...weird casting huh.. my mistake..I mean venom.. but isnt Venom like really Bulky??
wikipedia's not the most reliable source... and yeah, people said the same thing about toby. he can bulk up enough. not standard eddy brock size but at LEAST ultimate spidey eddy size. just have to wait and see. I'm sure Raimi and crew wouldn't cast him if he couldn't act the part well enough.
It says "info is subject to change completly". I wont believe it until I see pictures/trailers of topher grace as venom.
