Though no stars were photographed, confirmed sightings of Chris Evans and two other Avengers: Age of Ultron actors are revealed in set reports, while photos allude to a 1940s flashback. Check it out!

Filming for Avengers: Age of Ultron picked up today at the Rivoli Ballroom in London, England, where several extras were seen dressed in 1940s military garb. Observation would suggest there will be a flashback in the 2015 Marvel sequel involving Steve Rogers, which Chris Evans himself hinted at during an interview last month. However, Evans was joined by his Captain America co-star Hayley Atwell (aka Peggy Carter) for the said scene(s), but they weren't alone. A reliable source reports that British actor Paul Bettany, whose longtime Iron Man voice role J.A.R.V.I.S. will become the humanoid Vision in Age of Ultron, was also on set today. So, what exactly could this scene entail involving Steve Rogers, Peggy Carter, the Vision, and a 1940s ballroom setting? While you're thinking that over, check out some photos taken by Jasmine Bailey and Winne Kataka.
