Bradd Pitt vs. the undead. Hell, he already has six kids, how hard can it be? The World War Z movie has been through some pretty rough times, going back for extensive reshoots after test audiences crapped all over it. Now Paramount is giving it another shot with an ad during the Super Bowl. Because I don’t like to make you wait for things, here’s the trailer right now. Pitt plays a U.N. worker trying to stop the zombie pandemic before it overtakes the entire civilized world. We all know how well that works out. World War Z opens June 21st.
