Marvel Studios screened some concept art and proof of concept footage as well as a behind-the-scenes look at Thor: Ragnarok, which just recently began filming in Australia. In addition to quick glimpses of Hulk in his battle armor and the god of thunder with close-cropped hair and war paint, the conceptual footage also revealed two more adversaries that Thor and Hulk will face-off against in the third entry. We got a look at the Fenris Wolf, a being inspired by Fenrisulfr of Norse mythology.
