New trailer for the upcoming action sci-fi movie, Lock-Out. The story is pretty simple. The president’s daughter, played by Maggie Grace, who you might remember as Shannon from Lost is caught in a space prison with a bunch of mentally disturbed convicts. The only man who can save her is apparently Guy Pearce, who plays the character of Snow. The premise is very similar to Escape from L.A., but who cares it looks like a lot of fun. Lock-Out hits theaters April 20th, 2012.
