But attendees on Tuesday got a look during a tough knuckles behind those smiles — on both sides — as stretched negotiations pennyless into open over how Walt Disney Studios and a AMC museum sequence should separate sheet revenue.

Disney, now arguably home to a biggest brands in moviedom (Pixar, Lucasfilm and Marvel among them) is seeking softened terms; film studios do this from time to time, and Disney has not revised a contracts in years. It has already cumulative new deals covering some-more than half of a nation’s theaters.

But AMC Entertainment, a second-largest museum sequence in North America behind Regal, is balking and halted allege sheet sales for “Iron Man 3” to uncover a resolve. “We wish to strech agreement and get tickets on sale as shortly as probable so it doesn’t impact opening weekend,” AMC pronounced in a statement.

A Disney orator declined to comment. Disney was scheduled to make a CinemaCon display on Wednesday.

That such a brawl would turn open is unusual, though this might be a bit of a snowstorm in a teapot: AMC, acquired final year by a Chinese company, is not boycotting “Iron Man 3” altogether. That would be a reticent business move: “Iron Man 3,” set to arrive on May 3, is approaching to be one of a biggest hits of a year.

Studios and museum owners separate sheet sales according to formidable formulas. As most as 75 percent of a movie’s opening-weekend income might go to a studio, though in after weeks a commission typically becomes most some-more auspicious to theaters.

CinemaCon 2013 has differently been a frolicsome affair, with exhibitors especially impressed with what they saw on Tuesday from Warner Brothers. Jeff Robinov, Warner’s film chief, denounced footage from arriving films like “The Great Gatsby” and “Man of Steel” in a sharp-witted display that was a thespian alleviation from a pretentious one he gave final year.

Mr. Robinov particularly took time out of his debate to make good with Legendary Pictures, a vital film prolongation association and banker that has during times had a irritable attribute with Warner. Speaking of “42,” a Legendary film about Jackie Robinson that became an astonishing strike for Warner final weekend, Mr. Robinov said, “You done an extraordinary movie. You guys did an overwhelming job.”
