Actually it had nothing personal to do with the two stars. Appian Way, which is Leonardo DiCaprio's production company vs. Brad Pitts' Plan B company. They went lawyer to lawyer on a bidding war for the rights to the new movie based off of Max Brooks' Zombie book. They spent all day tossing out bids, finally, by morning they had a winner. Brad Pitt's Company won out the rights to World War Z.
Watch for the upcoming movie, "World War Z" in theaters near you. Now to see who will play in the movie.
