Iranian authorities are planning to sue Hollywood over Ben Affleck's Oscar-winning film "Argo" as a result of the movie’s allegedly "unrealistic portrayal" of the country, according to reports.

French attorney Isabelle Coutant-Peyre is in Iran for talks with officials over how and where to file the lawsuit.

"We will be able to block distributors of the movie, force them to apologize and challenge them to confess that the movie is nothing but a sheer lie," Coutant-Peyre told the Mehr news agency.

The decision to file suit was reportedly made after a group of Iranian cultural officials and movie critics screened the film in a closed audience in a Tehran theater late Monday.

Those in attendance dismissed Argo as a “violation of international cultural norms” and issued a statement saying that, “awarding an anti-Iran movie is a propaganda attack against our nation and entire humanity,” according to reports.

The film, which won an Oscar for best picture in February, recounts the 1979 attack on the U.S. Embassy in Tehran, which resulted in 52 Americans being held hostage for 444 days. It highlights the story of the six embassy staffers who were sheltered by the Canadian ambassador and managed to escape using a fake movie as a cover story.
