It seems that the writer of the next Peter Parker advenure will also be writing a film centering on one of his enemies. According to The Hollywood Reporter's Heat Vision Blog, Spider-Man 4 screenwriter Gary Ross will also be writing a Venom spin-off film as well.
The villain appeared in Spider-Man 3, portrayed by Topher Grace, and there has been talk of a spin-off film for quite some time now, and it seems to be moving forward with Ross' involvement. The studio wouldn't comment on whether or not Grace would return to reprise his role as Venom.
It was also reported that Ross may direct the film as well, with Avi Arad and Marvel Studios producing.
