Doug Liman has heaped praise on actress Naomi Watts.
The pair have joined forces for new movie Fair Game, in which Watts plays a CIA agent Valerie Plame, and Liman believes that it's one of the best performances from the actress.
Speaking to MovieLine the filmmaker said: "It's the best she's ever been. She is just extraordinary in the film.
"I don't think there's anybody - I don't care how hardcore Republican they might be - who's not going to look at the film and say, 'That was an extraordinary performance. That was a once-in-a-lifetime performance'.
"I think 'Fair Game' is in the spectrum of, 'It's a really great movie'. And a lot of other movies that have been about the war or dealt with the war have not been great movies."
Fair Game is the first movie for Liman in the director's chair since Jumper back in 2008 in what is only his seventh movie as a filmmaker.
The film reunites Watts with Oscar winner Sean Penn, who she starred alongside in 21 Grams.
Plame's status as a CIA agent was revealed by White House officials allegedly out to discredit her husband after he wrote a damming piece in the New York Times in 2003 about Bush and the Iraq war.
Joseph Wilson suggested that Bush and his administration had manipulated intelligence about weapons of
mass destruction to justify the invasion of Iraq.
