Following today’s extended trailer, an Avengers: Age of Ultron featurette has been released, and it goes behind the scenes of the highly-anticipated blockbuster. It’s very cool to see how the production puts together their big set pieces, and it was also neat to see some of the practical effects like real pyrotechnics going off in the background mixed with live-action stunt doubles being yanked around. The featurette also reveals that they’re shooting in more distant locations than ever before (Italy, South Africa, and Seoul), the first sequence they shot was Hulk versus Iron Man’s Hulkbuster Armor, and to quote Joss Whedon, “Mass destruction: Check. Superheroes check: Check. Beautiful locations: Check.”
Hit the jump to check out the Avengers: Age of Ultron featurette. The film opens in 3D on May 1, 2015 and stars Robert Downey Jr., Chris Evans, Scarlett Johansson, Chris Hemsworth, Mark Ruffalo, Jeremy Renner, James Spader, Elizabeth Olsen, Aaron Taylor-Johnson, Paul Bettany, Don Cheadle, Andy Serkis and Samuel L. Jackson.
