Well, the long debate over who will be Thanos is now over. Ever since that teasing glimpse of the character at the end of 2012's The Avengers, fans have wondered who'd be playing the Mad Titan. Well, wonder no more, as today, Variety reports that Josh Brolin (No Country for Old Men, Planet Terror, and Jonah Hex) has signed on to play the character, beginning in this Marvel's August entry: Guardians of the Galaxy.
No word yet on whether they signed him, like upcoming Avengers villain Thomas Kretschmann, to a multi-picture deal (Variety assumes this, but it hasn't been fully confirmed). But it's more than likely they have.
We'll update you with more information on this developing story as it becomes available.
