has been vague about Grace's role, stating only that Topher Grace will play "a complex role" which will contrast with the comedic, wholesome, or good-natured roles he's most known for playing. That is one of the reasons why many believe that he will be playing Eddie Brock, better known as Venom. (see paragraph 4)
I mean WTF??? Topger Grace can not play venom. Venom is suposed to be ****ing huge, muscular and strong. Its bad enough that they have a wimp as spiderman. They cant ****ing ruin the coolest villan ever aswell
