Channing Tatum channels his inner John McClane in the first trailer for director Roland Emmerich's White House Down. The actor portrays John Cale, a cop who is touring the White House with his daughter, when 1600 Pennsylvania Ave. is taken over by a paramilitary group who kidnaps the President of the United States (Jamie Foxx), making John the only one who can save the commander-in-chief's life. Take a look at the first footage from this action-thriller, along with two new posters featuring Channing Tatum looking worse for wear.
