Hollywood stars currently visiting the Islamic Republic on a cultural tour have been barred from meeting with Iranian cinema officials.
"Cinema officials will only have the right to have official sessions with...Hollywood movie makers when they apologize to the Iranians for their 30 years of insults and slanders," Javad Shamaghdari, art advisor to Iranian President Mahmoud Ahmadinejad said in a statement.
Nine members of the Academy of Motion Picture Arts and Sciences arrived in Tehran on Friday.
Shamghadri mentioned "The Wrestler" and the war epic "300" as productions that "unjustly attack" Iran. The war film depicts an Iranian ancestor as bloodthirsty, and "The Wrestler" included a scene of tearing the Iranian flag.
"We will believe (United States President Barack) Obama's policy of change when we see change in Hollywood too, and if Hollywood wants to correct its behavior towards Iranian people and Islamic culture then they have to officially apologize," Shamaghdari added, the Iranian students news agency reported.
Hollywood producer Sidney Ganis, who led the visitors, said they traveled "to communicate with our fellow filmmakers" in the Islamic Republic in "an exchange of ideas relating to the making and distributing of movies."
"We have an art form here that is universal and so very accessible around the world. That is a good thing to make use of that art form in expressing ideas," he told Los Angeles Times.
Ganis said he is prepared for further cooperation between Iranian and American filmmakers.
