Actor-director Ben Affleck visited Central Intelligence Agency (CIA) as part of his research for his Oscar-nominated film "Argo".
The 40-year-old undertook extensive investigations for the film, which follows the real-life story of US diplomats, who were taken hostage in Iran in 1979. He wanted to ensure his dramatisation remained accurate to true accounts.
"I really liked the idea that it was a true story. I did a ton of reading and a ton of interviewing. I went to the CIA, I read all the books," femalefirst.co.uk quoted Affleck as saying.
"I spent time with (CIA agent)Tony Mendez and for the first-person accounts of this, then I did a lot of researching with hostages," he added.
