Washington, Feb 24 : Oscar winner Sean Penn is in talks to star in Fair Game based on the real life of CIA agent Valerie Plame.

Naomi Watts has been roped in to play the lead while Penn is in negotiations to star as Ambassador Joseph Wilson.

Wilson watched his wife''s CIA status become compromised after he wrote op-ed columns that accused the Bush Administration of manipulating intelligence about weapons of mass destruction to justify the invasion of Iraq, reports the Variety.

Plame Wilson left the CIA in 2005 and she and her husband filed a civil suit against Vice President Dick Cheney, Karl Rove and Cheney''s ex-chief of staff, Lewis "Scooter" Libby.

While Rove and Deputy Secretary of State Richard Armitage admitted they leaked her agency status to journalists, Libby was convicted of lying to a federal grand jury about his role in compromising her covert status.

The film will be helmed by `Mr. and Mrs. Smith' director Doug Liman. (ANI)
