Marvel fans, listen up. Eminem's got some music up his sleeve for the forthcoming Venom movie.

Shady took to Twitter on Thursday (Aug. 30) to upload a 15-second clip of his song for the film, featuring an explosive beat and the ominous lyrics: "Knock, knock, let the devil in."

Venom, out October of this year, follows the story of one of Marvel's biggest villains discovering his superpowers after he becomes host to an alien parasite.
