The heads of cinemas in 193 small towns in the country are boycotting the superhero sequel, with a total of 686 screens missing out on the blockbuster, according to German publication Deutsche Welle.

Theatre owners told the Deutsche Welle that they were stunned to learn Disney's new rental fee went up to 53 per cent of ticket sales from 47.7 per cent. They also claim Disney bosses have reduced their advertising budget in Germany and refused to provide advances for 3D glasses.

Karl-Heinz Meier, a spokesman for advocacy group I.G. Nord tells the publication, "We are worried, particularly about eastern Germany. When prices go up, then we have a serious problem that could force movie theatres to close."

The film, which stars returning Avengers Robert Downey, Jr., Scarlett Johansson, Chris Hemsworth and Chris Evans, has already debuted with a $201.2 million (£125.8 million) haul at the global box office, a week before it opens in the U.S. and Canada on Thursday (30Apr15).
