I'd be curious to find out if Brad Pitt has a particular connection to World War II because he might be starring in a third film that takes place in that setting.  In 2010, he starred in Inglourious Basterds; this year, he'll be leading David Ayer's WWII tank film Fury; and now he might have an untitled romantic thriller in the cards.  According to Deadline, Pitt is circling an untitled WWII movie written by Steven Knight (Eastern Promises).  Additionally, Deadline is hearing "it’s serious and that a big director will be set with an eye toward starting production early next year."

Keep in mind that Pitt is always in demand, which means he has the power to be very selective in his projects.  He's being eyed for Go Like Hell, he could do Pontius Pilate, and then the big one is a sequel to World War Z, which is the most likely contender since he's also a producer on that film.  It will be interesting to see what he takes as his follow-up to Fury, which opens on November 14th.
