It looks like Loki breaks out of his glass cage in this new poster from Thor: The Dark World. We know that Thor teams up with the God of Mischief in this sequel, and it's safe to say that we know he's going to turn on Thor in the end. I think we might be left with an unhappy ending this time around, but we'll see. We also have an international poster for the film featuring Anthony Hopkins as the epic God Odin.
The movie is set to hit theaters later this year on November 8th!
