We already knew that next month’s Thor would feature an appearance by Marvel’s bigscreen shaman Samuel L. Jackson as Nick Fury (not to mention Fury’s right-hand man Agent Coulson). But there have been rumors that one of Thor’s future Avengers teammates would also stop by for a cameo. A new video clip released may hold a clue: In the middle of a fight sequence, there’s a sudden cut to a shadowy figure…who is pointing a rather impressive-looking bow at the thunder god. Could this be our first sighting of Jeremy Renner’s Hawkeye? Marvel Studios hasn’t responded to EW requests for confirmation, so you’ll have to decide for yourself by watching the video after the jump. (The maybe-Hawkeye guy is at the 0:24 mark.)
