TEHRAN — A tough week for Ben Affleck just got tougher.

First, he was snubbed in the Oscar nominations on Thursday, overlooked in the best director race for “Argo,” his film about the Central Intelligence Agency’s extraction of six American diplomats from revolutionary Tehran. Now, news reports from Tehran say the Iranian government is planning to finance a movie that will correct what it says are numerous distortions of the historical record in “Argo.”

Not much is known about the proposed movie, other than its title, “The General Staff,” and its director, Ataollah Salmanian, a minor figure in Iran’s cinema industry. But it is a sure bet that it will center on the official Iranian view of the 1979 hostage crisis, in which 52 American diplomats were held by Islamic students for 444 days.
