(CNN) -- A government-linked film studio in Iran plans to make a movie about the Iranian nuclear scientist who Iranian officials say was kidnapped by U.S. agents, state media reported Tuesday.

According to Iran's semi-official Fars news agency, Sima Film production company has hired a group of film school graduates to write a script about Shahram Amiri. The head of the production company didn't say when the film would be ready.

Amiri received a hero's welcome when he returned to Iran last week.

U.S. officials say he defected to the United States, and one official said Amiri received approximately $5 million for providing the U.S. government with "valuable, original information" on Iran's nuclear program.

Amiri apparently posted conflicting video messages on the internet when he surfaced in the United States. In one, he said he was in the United States voluntarily studying for his Ph.D. In another, he changed his story and said he had been kidnapped by U.S. agents but had escaped.

Upon his return to Iran, Amiri, who is a researcher from Tehran's Malek Ashtar University, repeated his claims that he was kidnapped.

"I was abducted in Medina ... Then I was transferred to an unknown location in Saudi Arabia," Amiri told Press TV. "They injected anesthetic drugs into me. They took me to the United States on a military plane.

"During my stay in the first two months, I was subjected to heavy psychological and mental tortures by CIA interrogators," he said. "Other kinds of pressure too. They told me if I don't cooperate with them, they will hand me over to Israel and there are hidden prisons in Israel and there will be no

trace of you any more."
