josh brolin thanosThe big bad of "Guardians of the Galaxy" has been a big mystery ... until now.

As Marvel fans well know, the villain of the upcoming comic book adaptation is Thanos, the powerful and insane mutant from Titan. Thanos was teased at the end of "The Avengers," and will reportedly be a the adversary in "The Avengers 3." But exactly who is playing Thanos has been the question.

Latino Review claims to have an answer: They're reporting that Josh Brolin has been tapped to voice the purple-skinned evildoer. (Update: Variety confirms that Brolin has been cast as Thanos.)

Of course, neither Marvel nor Brolin's reps have confirmed the news, but the actor would be a great choice; his deeply resonant voice can come across as dark and ominous.

We'll have to wait and see when "Guardians of the Galaxy" hits theaters on August 1.
