Nicole Kidman is set to play the CIA Agent who's cover was blown, Valerie Plume, in a film of her memoirs Fair Game: My Life as a Spy, My Betrayal by the White House.

However the director Doug Liman, who seems an unusual choice, reveals a little of his approach and how it might all be filmed, and it sounds intriguing, even if he hasn't proven it will work as yet.

Valerie Plume's story was itself heavily censored by the CIA before being released, and the concern is that the film will go the same way. It'll certainly take a lot of work to get it a release. However Doug Liman seems to be a good bet to get that done, but political spy thriller? Surely we'll end up more like Bourne and the Smiths?

In a nutshell, Plume was a CIA agent who was revealed to the press by the American government after she criticised their handling of the weapons of mass destruction in Iraq issue. It began a rather open and very political controversial affair and Plume's book followed soon after.

The announcement of Nicole Kidman playing Valerie Plume by MTV Movies Blog through First Showing isn't the most exciting part, of course it's great news and shows that this will be a pretty big film, but the real news is what Doug Liman is saying about the film and the style he's going to follow. It seems he has big plans...if it works.

Liman doesn't seem the obvious choice to me for a film that dives straight into such serious issues, however he seems to be excited about it and have some strong ideas.

"I have a really, really insane take on how to tell it. It's so outrageous. Ultimately, I'd be doing something no one has ever done before. Therefore it's automatically appealing to me. I'm just starting to explore whether [what I have in mind] is even possible to do...

Now that does sound interesting, and there's really nothing to sit and start guessing about because he just hasn't given us even the slightest hint of what he's going to do with the film.

The danger through is that this ends up being a Bourne Identity or Mr and Mrs Smith type film, something I really hope it doesn't. Interestingly Liman reveals that Kidman was his first choice for Mrs Smith.

"Nicole was supposed to play Jane Smith in 'Mr. and Mrs. Smith.' We owe a movie together! That's an unrequited thing between me and an actor where I fell in love with them for a role and never get to consummate it."

Well I think Kidman is a great choice, but is Liman? He certainly makes us think he has something very clever and new up his sleeve, and I'm keen to find out what.
