300 and Watchmen director Snyder has been rumoured for the director's chair on Justice League on several occasions now, and according to Gangster Squad helmer Ruben Fleischer, it's already a done deal. When asked by Screen Crush if he had any interest in directing the DC team-up, Fleischer responded that he's definitely keen to direct a superhero movie but it won't be Justice League, as "that's something that Zack Snyder is going to wind up doing."
Assuming Man of Steel is a success, Snyder would seem like the ideal choice for Warner Bros., especially now that Christopher Nolan has officially distanced himself from any involvement. However, the director was remaining tight-lipped about the studio's plans post-Man of Steel in an interview with Empire, although he did acknowledge the franchise expectations for the reboot, as well as confirming that Man of Steel will include nods to a wider DC world:"We didn't design the movie like Batman [i.e. as a trilogy] but I don't think anybody would say you design a Superman movie as a one-off... I have been making references to the DC Universe, just to let you know that world is out there..."
Man of Steel is set for release on June 14th, with a cast that includes Henry Cavill (Immortals) as Clark Kent / Superman, Amy Adams (The Fighter) as Lois Lane, Russell Crowe (Les Miserables) as Jor-El, Michael Shannon (Boardwalk Empire) as General Zod, Kevin Costner (Hatfields & McCoys) as Jonathan Kent, Diane Lane (Secretariat) as Martha Kent, Laurence Fishburne (Contagion) as Perry White, Ayelet Zurer (Angels & Demons) as Lara Lor-Van and Antje Traue (Pandorum) as Faora.
