Iranian authorities are reported to be planning to sue Hollywood over the Oscar-winning Argo because of the film's allegedly "unrealistic portrayal" of the country.
Several news outlets, including the pro-reform Shargh daily, said that French lawyer Isabelle Coutant-Peyre is in Iran for talks with officials over how and where to file the lawsuit.
Ms Coutant-Peyre is also the lawyer for notorious Venezuelan-born terrorist Ilich Ramirez Sanchez, known as Carlos the Jackal.
The decision on the lawsuit came after a group of Iranian cultural officials and movie critics screened the film in a closed audience in a Tehran cinema on Monday.
Last month Iranian officials dismissed Argo as pro-CIA, anti-Iran propaganda.
The film is based on the escape of six American hostages from the besieged US Embassy in Tehran in 1979.
