Iranian authorities are planning to sue Hollywood over the Oscar-winning movie "Argo."

Iranian media reports authorities are angry over the movie's allegedly "unrealistic portrayal" of the country, calling it pro-CIA and anti-Iran propaganda.

Argo is based on the escape of six American hostages from the U.S. Embassy in Tehran in 1979.

French lawyer Isabelle Coutant-Peyre is reportedly in Iran talking with officials about whether to file suit.

The lawyer once defended the notorious Venezuelan-born terrorist Ilich Ramirez Sanchez, known as Carlos the Jackal.
