I finally just realized why I’m psyched for Knight and Day. I can totally relate to a woman (Cameron Diaz) who wouldn’t, at first, be all that excited to be essentially held hostage by a spastic, possibly mentally unstable man, played by Tom Cruise. But then you realize how fun it could be — he’s always going to kick ass, and you get to use double guns — and you kinda warm to the idea. Especially after the beach scene, which makes you think fondly of Cocktail. If Knight and Day is half as fun as Mr. & Mrs. Smith was, it’ll be a good summer action flick. Watch the latest trailer embedded after the jump.
