Following Joss Whedon's apology to the people of South Korea for filming in Seoul, “Avengers: Age of Ultron” kicked off production Sunday, March 30 with Captain America jumping into action, TheWrap said.

Set footage shows a costumed Cap pumping himself up and then leaping onto a moving semi truck once the cameras start rolling.

It's not clear if it is actor Chris Evans or a stunt double getting to work on the upcoming Marvel movie, but it is clear that the superhero who works for S.H.I.E.L.D. will be particularly interested in a South Korean genetics company called “U-Gin” when “Age of Ultron” hits theaters on May 1, 2015.

The footage also serves as free, and timely promotion for Marvel's latest release, “Captain America: The Winter Soldier,” which is already a hit overseas and is expected to be on in the U.S. when it opens on Friday.

“Avengers: Age of Ultron” features an ensemble cast that includes Robert Downey, Jr., Chris Hemsworth, Mark Ruffalo, Chris Evans, Scarlett Johansson, Jeremy Renner, Samuel L. Jackson, Aaron Taylor-Johnson, Elizabeth Olsen and James Spader.
