What would happen if everything on Earth evolved to kill people and the human race had to abandon the planet, but then—scores of years later—noted alien slayer and Philly native Will Smith, and his son Jaden, crash landed back on the third rock from the sun? Director M. Night Shyamalan's After Earth examines that exact scenario. Will and Jaden Smith—and Shyamalan—spent a bunch of time in and around Philly while filming the flick. Check out the trailer and remember, fear is a choice.
