TEHRAN — Iran is planning to sue Hollywood over “Argo” because of the Oscar-winning Best Picture’s “unrealistic portrayal” of the country, local media reported yesterday.

Following the 1979 attack on the US Embassy in Tehran, 52 Americans were held hostage for 444 days, but six embassy staffers were sheltered by the Canadian ambassador.

Their escape, using a fake movie as a cover story, is recounted in “Argo.”

The decision on the lawsuit came after a group of Iranian cultural officials screened the film in a closed audience late on Monday. The gathering, entitled “The Hoax of Hollywood,” discussed various legal aspects of filing a lawsuit, although it remains unclear what specific charges Iran could raise and what court Tehran could turn to if the action goes ahead.

Those at the meeting dismissed “Argo” as a “violation of international cultural norms.”
