Paramount and Marvel have released a pair of new posters for the forthcoming Thor, starring Chris Hemsworth and directed by Kenneth Branagh. And despite the fact that these are posters numbers twelve and thirteen for the film’s marketing team, we’re giving them some time. Why? Because they are ripe with intensity as Thor (Hemsworth) and his bad brother Loki (Tom Hiddleston) stare each other down. Nothing says epic intergalactic brouhaha like a simple bit of sibling rivalry. Check out both posters for yourself after the jump.

Thor is in theaters May 6, 2011.
