What you need to know about the Spider-Man villain who appears in the ‘Venom’ after-credits scene


Warning: This post contains spoilers for the after-credits scene of “Venom.”

  • The “Venom” after-credits scene features actor Woody Harrelson as the serial killer Cletus Kasady, who in the comic books becomes the Spider-Man/Venom foe, Carnage.
  • In the comics, the Carnage symbiote is an offspring of Venom that bonds to Kasady in prison.
  • In the scene, Brock visits Kasady in prison, who vows “there’s gonna be carnage” when he escapes.
  • With “Venom” a box-office hit, there’s bound to be a sequel – and more Carnage.

Comic book readers were probably not surprised to discover who the “Venom” after-credits scene introduces to the Sony Spider-Man expanded universe: Cletus Kasady, the serial killer who becomes the symbiotic monster and one of Spider-Man’s most popular foes, Carnage.

But even fans were likely taken aback by who portrayed the character in the scene: none other than Woody Harrelson, complete with a curly red wig. The scene features journalist Eddie Brock, played by Tom Hardy, visiting a prison to interview Kasady. When Brock arrives, Kasady has written “Welcome Eddie” in his own blood on the wall, and proclaims that when he escapes, “there’s gonna be carnage.”

For non-comic book readers, the scene – like many world-building after-credits scenes in superhero movies today – may have been a tad confusing. Who is this guy and why should casual moviegoers care?

In the comics, Carnage is an alien symbiote (or parasite) that is the offspring of Venom. When Venom bonds with Brock, he is in prison along with his cellmate, Kasady. The Carnage symbiote bonds with Kasady after Venom/Brock escape prison, setting up the long-running conflict between Venom and Carnage, in which Spider-Man has regularly been caught.

Since Kasady is a cold-blooded murderer, Carnage is more vicious than Venom, and hence doesn’t have some of the barriers that Venom has shown in the comics and the movie.

In an interview with IGN, “Venom” director Ruben Fleischer said that the movie slightly deviates away from Carnage’s comic-book origin story so that Brock/Venom could be developed as an anti-hero that the audience roots for before introducing Carnage.

“I don’t think we wanted Eddie to go to jail at the end of our movie,” Fleischer said. “That would have been a bit of a bummer. But we did want to have them in jail cell proximity and so we left the door open for how Venom can spawn Carnage and how Cletus might someday become that character.”

The “Venom” movie alludes to the idea that there are hundreds more symbiotes from their home planet, and that we only saw a sliver of them. Whether a sequel sticks to the idea that Carnage is an offspring of Venom or an entirely separate symbiote remains to be seen.

Fleischer also said that the ambition “was to show that there are legs for the franchise in that a fan favourite let alone played by Woody Harrelson would be something we could look forward to in the future.”

“Venom” is a surprise box-office hit, smashing expectations in its opening weekend with $US80 million – the biggest October opening of all time. It’s also made over $US225 million worldwide. With a production budget of $US100 million, it’s safe to say that there will be a sequel to “Venom.”

That means more Carnage.
