Sony has unveiled the second trailer for the action thriller White House Down [WHDWN]. Channing Tatum [CTATU] plays a police officer who wants to be a Secret Service agent and happens to be in the White House when terrorists attack Washington D.C.. Somehow, he is the last man left to protect the U.S. President, played by Jamie Foxx [JFOXX], and the film turns into a buddy cop comedy. The attempt at an "Get off my plane!" punchline from Air Force One comes up just a bit lacking. Playing like the lighter version of Olympus Has Fallen, White House Down goes down June 28th.
