Avengers: Age of Ultron director Joss Whedon is being top-secret about Marvel’s newest film, but someone still managed to get in there and leak something interesting. The person caught some of the gang actually in the midst of filming a scene at the UEA Campus Norwich in England. We see a group of uniformed people running together (new recruits for S.H.I.E.L.D.?) and later, Thor, Stark, and Cap chatting. The cool part comes when Thor lifts his hammer to summon lightning, although it doesn’t seem to make a lot of sense for that to happen mid-conversation. It’s said that the film is more than halfway through production, so maybe soon we’ll have some official info from Marvel and Whedon as to what might be going on.
