Marvel Comic-Con panel videos: Loki arrives and Karen Gillan shows shaved head

Marvel Studios might not be rolling out the exclusive "Thor: The Dark World," "Captain America: The Winter Soldier" or "Guardians of the Galaxy" footage that was shown during the studio's San Diego Comic-Con panel, but at least video has been released of the other two most talked about moments from the event.

First Tom Hiddleston took over Hall H in character as Loki, and then Karen Gillan whipped off her red wig to reveal that she had shaved her head for her "Guardians" role. Both of these big moments had the crowd going wild, as can be seen in these two videos.

Are you excited about Marvel's upcoming movie slate? Did you like the reveals at Marvel's Comic-Con panel?
