The first leaked images have emerged from the set of Avengers: Age of Ultron, which is currently in production in Johannesburg, South Africa.
The filming shows scenes of destroyed cars, and people fleeing in terror.
According to one local, Ismail Ebrahim, the key figure in the scene was the Hulk.
“I could see some sort of action scene where Hulk was battling someone but not too sure who was it,” said Ebrahim, in comments to ComicBookMovie.com.
“I could make it out clearly because they use a huge green head whenever they’re filming Hulk scenes.
“They used a guy dressed normally but had on a backpack with two iron poles holding up hulk’s chest upwards and then he was doing whatever he had to do… scaring the people. By the looks of it, Hulk will probably play a major role in the Johannesburg shoot.”
The news site reports that only the first ten minutes of the film will be shot in Johannesburg, with the remainder being shot in the UK from April.
Avengers: Age of Ultron is scheduled to be released to theatres on May 1, 2015.
