"Slither" director James Gunn belongs in a rare class, having directed superhero films for both Marvel Studios and DC Films. He’s best known for bringing the ragtag team "The Guardians of the Galaxy" to life on screen. But earlier this year, Gunn also switched gears and created a super-villain adventure in "The Suicide Squad," which is coming to 4K, Blu-ray and DVD beginning on October 26. Gunn sat down with CinemaBlend to dig into spoilers for "The Suicide Squad" ahead of the home video release. And as we spoke, he revealed to us that he’s a mere three weeks away from day one of shooting on "Guardians of the Galaxy Vol. 3," a sequel that just announced the actor playing Adam Warlock in the MCU. When laying out for CinemaBlend just how busy these next few weeks are going to be, Gunn let slip the participation of a key "The Suicide Squad" collaborator following him from DC to the MCU, and that’s composer John Murphy.
