The next instalment of Marvel's Hollywood blockbuster franchise Avengers, Age of Ultron, has joined other movies that have been filmed in the streets of Johannesburg.

Avengers: Age of UItron is an American film based on the Marvel Comics superhero team the Avengers. It is scheduled to be released in theatres later this year – first on 22 April in Italy.

Filming began on Tuesday, 11 February 2014 in Johannesburg when the second unit crews shot action sequences in downtown Joburg for a fortnight without the main cast. These are to be used as background plates for scenes featuring the Hulk.

The Gauteng Film Commission showcased the city to Marvel Studios in 2013, when it spoke about Johannesburg's physical assets and the benefits of filming in the region. These include the possibility of qualifying for the revised government film incentive, which is intended to attract large-budget films and television productions. These are expected to contribute towards employment creation, enhancement of South Africa's international profile, and increase the country's creative and technical skills base.

Avengers: Age of Ultron follows the likes of District 9, Catch a Fire, Dredd, Invictus and Hotel Rwanda, which were all shot in Gauteng.

The movie is the sequel to Marvel's The Avengers, released in 2012. The film was scripted and directed by Joss Whedon and features an ensemble cast that includes Robert Downey Jr, Chris Hemsworth, Mark Ruffalo, Chris Evans, Scarlett Johansson, Jeremy Renner, Don Cheadle, Aaron Taylor-Johnson, Elizabeth Olsen, Paul Bettany, Cobie Smulders, Stellan Skarsgård, James Spader, and Samuel L Jackson.
