Infamous writer/director Douglas McGrath has signed up to direct The Lucky One, an adaptation of Nicholas Sparks' Iraq War-set romance for Warner Bros.

The Lucky One in question is a US Marine who attributes his survival through three tours in Iraq to his lucky charm, a photo of a smiling woman he carries with him. When he returns home to North Carolina he tracks down the mysterious lady and romance ensures. Or does it?

Frankly, we're not sure, but if you were to expect a heart-string tugging romance with a tinge of melodrama, you'd probably not be too far wrong. Sparks' novels have been adapted into movies with Grisham-esque regularity - he's the man behind The Notebook, Message In A Bottle, A Walk To Remember, Night In Rodanthe, which should give you some idea of what to expect.

McGrath, meanwhile, has a strong track record in literary adaptations. Prior to his Truman Capote biopic Infamous (ok, more of a literally themed film than an actual adaptation), he directed Nicholas Nickleby and the Gwyneth Paltrow-starring Emma.

The Lucky One reunites McGrath with his Night In Rodanthe producer Denise Di Novi, who will signing the cheques for Warner Bros.
