Production has begun in Johannesburg, South Africa on Joss Whedon's superhero sequel Avengers: Age of Ultron. It will be on location for the next two weeks. They are also slated to film in northern Italy and South Korea.

They have shut down Albertina Sisulu Road in the city from 7am to 7pm between Harrison and Rissik streets. Certain other roads are being closed 24 hours a day. General traffic is being omitted until production wraps in the area.

Here is what Gauteng Film Commission chief executive Phindile Mbanjwa had to say about the production.

"We're thrilled that Marvel Studios is bringing a major motion picture project to Joburg, and we're committed to showing them the very best our region has to offer."

Mayor Parks Tau added.

"It strengthens Johannesburg's position as a worldwide film production centre with first-class facilities and production support."

In our story from /avengers-age-of-ultron-is-south-africa-not-doubling-for-wakanda/yesterday, it was reported that Johannesburg is being shot as Johannesburg and will not double for Wakanda, homeland of T'Challa (aka Black Panther). No main cast members are a part of the shoot, with many speculating that Johannesburg could serve as the initial home to Baron von Strucker (Thomas Kretschmann), Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen). The first ten minutes of the movie are being shot here, and it is believed that Baron von Strucker is the Avengers' original target in the beginning of the movie, and that he serve to introduce superheroes Quicksilver and Scarlet Witch to the team.

It's still possible that the sequel will feature a reference to Wakanda, since the studio is developing a Black Panther movie that may be featured in Marvel's Phase Three. In the Marvel comics, Wakanda is not only the homeland of Black Panther, but also where vibranium is found, the indestructible metal used to create Captain America's shield.
