X-Men and Assassin's Creed actor Michael Fassbender is teaming with Broad Green Pictures and Storyscape Entertainment on the true story Entering Hades. The film will center on journalist and serial killer Jack Unterweger, who led a double life "investigating murders by day and killing by night." Throughout his serial killing career, Unterweger killed 11 people across multiple continents. Conor McCaughan (Assassin’s Creed, Slow West) and Daniel Emmerson (Assassin’s Creed) of Fassbender’s DMC Film will produce the film alongside Storyscape's Bob Cooper (John Tucker Must Die) and Richard Saperstein (Se7en). Birdman writer Alexander Dinelaris is rewriting the screenplay with Fassbender eyed to star.
