Several news outlets, including the pro-reform Shargh daily, said on Tuesday that French lawyer Isabelle Coutant-Peyre is in Iran for talks with officials over how and where to file the lawsuit. 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 theater late Monday.
Iranian officials in February dismissed "Argo" as pro-CIA, anti-Iran propaganda.
The movie is based on the escape of six American hostages from the besieged U.S. Embassy in Tehran in 1979.
