Marvel‘s Guardians of the Galaxy lies just around the corner with a August release date, and Avenger: Age of Ultron out next May. Even with those release dates looming, the voice of Thanos has apparently been mysteriously cast for months. The villain has already even completed his work for Guardians of the Galaxy.

Deadline (without any confirmation from Marvel Entertainment itself) is reporting that its sources have named Josh Brolin (Goonies, Men in Black 3, Sin City: A Dame to Kill For) as the major role replacement to the minor role previously held by Damon Poitier in The Avengers. So with Josh Brolin behind the character expect a lot more from him between these two movies.

We’ll be sure and keep you posted on the latest for Guardians of the Galaxy and Avengers: Age of Ultron.
