What do we know about the bad guys in the upcoming Avengers movie in production..
The main bad guys are Loki (as seen in the Thor movie – since he gets hold of the Cosmic Cube at the end of that movie), and of course the green-skinned reptilian alien Skrulls.
But there’s yet another big villain to come in this movie!
SPOILERS as River Song would say..
None other than THANOS!!!
