Venom (Gary Ross)

Venom is a proposed spin-off film of the Spider-Man film series.

Plot
The film was to follow up the events of Spider-Man 4 and have Venom be portrayed as the antihero of the film.

Cast

 * Topher Grace as Eddie Brock/Venom
 * Beth Riesgraf as Anne Weying/She-Venom
 * Zachary Quinto as Carlton Drake/Riot

Why It Was Cancelled

 * 1) Sam Raimi chose not to make Spider-Man 4 and stated that he was unhappy with Spider-Man 3.
 * 2) The Amazing Spider-Man was going to be made, but with a different cast and director.

Result
While the Sam Raimi adaptation series has since been discontinued, a standalone Venom film has since been revived and is set to kick off a new shared universe that is adjunct to the Marvel Cinematic Universe.
