It's been quite busy on the Avengers: Age of Ultron set since filming began this morning at the University of East Anglia campus in Norwich, UK. Following shots of many Audi sports cars and what appears be part of The Avengers Tower, details and more photos have emerged. Potential spoiler warning! In addition to groups of uniformed "Avengers Recruits" extras, we also have blurry visuals of Chris Evans on set, as well as Robert Downey Jr., his stunt double, and the backside of Thor and Black Widow doubles. However, several sources from the set have sighted Chris Hemsworth, Samuel L. Jackson, Elizabeth Olsen, Aaron Taylor-Johnson, Anthony Mackie, and even actor B.J. Britt (Agent Triplett from Agents of S.H.I.E.L.D.) all in costume. Supposedly, someone also got a glimpse of the Iron Patriot armor, but actor Don Cheadle was nowhere in sight. Regarding what exactly is happening in the multiple scenes that are being filmed, photos and some Instagram vids show the aforementioned "Avengers Recruits" in training while Tony Stark himself was seen making an entrance in an orange Audi. And B.J. Britt was seen checking out a bike that this blog assumes belongs to Captain America. No word on what the others were up to, but check out the pics below!
