guardiansofthegalaxyCasting for Marvel’s Guardians of the Galaxy has grown into one hell of cast. The latest addition to join is Benicio Del Toro, but who he’ll play is unknown. It’s a character who will take part in multiple Marvel films, so this of course means rumors occur!

The nasty rumor about the role Del Toro will portray? One of Marvel’s ultimate villains, Thanos. You might remember him from the very end of The Avengers, flashing that dashing grin. But no, that wasn’t Del Toro in that scene. Obviously.

Del Toro is an incredible actor who could pull off the role, but it’s all speculation at this point. Though it’s fun to imagine.

He joins Chris Pratt, Zoe Saldana, Michael Rooker, Dave Bautista, Glenn Close, and John C. Reilly. Oh, and Karen Gillan of Doctor Who, who plays a villain in the movie.

Guardians of the Galaxy releases in theaters August 1, 2014.
