A rumor suggests that Woody Harrelson will be playing Carnage in the upcoming "Venom."
According to Bleeding Cool, Harrelson will most definitely appear in “Venom” in the role of the symbiote villain. I personally wanted a solo Carnage movie much more than a Venom, and that might just happen with Harrelson, especially if his appearance in the movie is met with success.
Carnage, aka Cletus Kasady, is the most R-rated comic book villain imaginable. In fact, an NC-17 rating is needed for some of the hijinks he's done in page. Marvel lore has Kasady growing up as a child and murdering animals, which to many experts is an early sign of a serial killer, which then leads to the murder of his grandmother and then it just escalates from there. Fun stuff.
