It is one of the most hotly-anticipated blockbusters, starring a string of Hollywood stars including Robert Downey Jr, Scarlett Johansson and Chris Hemsworth.
But with Avengers: Age of Ultron out in cinemas today people in Norwich will be watching closely to spot their city on the silver screen.
The follow-up to 2012's Avengers Assemble, which grossed more than £1 billion at the box office, filmed some scenes on location at the University of East Anglia's Sainsbury Centre for Visual Arts last summer on Friday, June 13.
Parts of the university campus were turned into a 'secret' movie location and area was awash with sightings of the film's superhero stars, including Chris Evans, who plays Captain America.
During filming a large 'A' sign for the Avengers could be clearly seen on the Sainsbury Centre's Modern Life Café, which had four high performance cars positioned outside. Today it emerged that the cafe was the location for the 'training ground for super heroes' scene in the film, with other scenes shot in the curved corridor and down by the lake.
The university was able to accommodate the auditions for between 20 and 120 extras, as well as accommodating the very strict security for the Hollywood stars' temporary accommodation, including the use of the helipad.
Robert Downey Jr, who plays Iron Man in the film, took the time to chat to Norfolk three-year-old Lewis Olsen, before the actor's helicopter took off from near the hospital after filming.
The Sainsbury Centre and the UEA provided very tight security throughout the operation, with the university providing discrete parking for up to 100 vehicles and transportation from the parking to the centre and film company praised the students' restraint and good manners from over-running the filming area.
The sequel, directed by Joss Whedon, sees the Marvel Comics superheroes forced into action when a high-tech peacekeeping programme - Ultron - goes badly wrong.
The film itself has been warmly received by newspaper critics, with several four out of five stars ratings.
