The Avengers Age of Ultron Set Report Potentially Reveals Numerous Cameos

The Avengers: Age of Ultron began filming at the University of East Anglia campus in Norwich, U.K. Friday morning, and the day seems to have been packed with plenty of goodies for fans who are closely following the news from the set.

Comic Book Movie has gathered some reports and pictures from the set that detail some juicy information about Joss Whedon's superhero sequel. Firstly, these photos show multiple Audi vehicles and depict the Avengers logo inside a building, possibly the interior of Avengers Tower.

This second batch of news states groups of uniformed "Avengers Recruits" extras were on set. The photos also show Chris Evans and Robert Downey Jr. on set, along with Downey's stunt double and the stunt doubles for Chris Hemsworth and Scarlett Johansson.

But perhaps the most interesting news comes from multiple sources on the set, who have spotted Chris Hemsworth, Samuel L. Jackson, Elizabeth Olsen, Aaron Taylor-Johnson, Anthony Mackie and B.J. Britt (who plays Agent Triplett on Marvel's Agents of S.H.I.E.L.D.) in costume.

But wait, there's more! One source also claims to have seen the Iron Patriot armor, though Don Cheadle was not there. As for the actual content of the scenes filmed today, various photos and Instagram videos show the "Avengers Recruits" in training and Tony Stark arriving in an orange Audi. B.J. Britt, meanwhile, was apparently checking out a bike, which could belong to Captain America.
