The El Capitan Theatre in Los Angeles hosted the United States premiere of Iron Man 3 on April 24. The film opened in 46 countries through April 22–24, with the United States release, in 4,253 screens, happening one week later. Regal Cinemas, AMC Theatres and Carmike Cinemas put presale tickets on hold, two weeks before the US premiere. The cinemas were in a contract dispute with Disney, who wished to receive more of the ticket sale profit than they currently did, largely based on the projected premiere-weekend intake Iron Man 3 was expected to have. Carmike was the first to come to terms with Disney. It was later reported that Cinemark Theatres had also stopped selling presale tickets, and Regal Cinemas had removed all marketing material for the film from its locations. On April 25, 2013, Regal, AMC and Disney ended their dispute, which allowed Regal and AMC to proceed with selling presale tickets again.
