Re-uniting Tom Cruise and Cameron Diaz for the first time since 2002's Vanilla Sky eonline has the first trailer for director James Mangold's new film Knight and day.

The film sounds like a different take on the Pitt/Jolie film Mr and Mrs Smith, but hey you can never tell from a synopsis, but the trailer does nothing to really sell the film.

Let���s wait for the next trailer as both these leads are likable and having a director on board with a back catalogue that includes Walk the Line and 3:10 to Yuma you can expect something good.

Check out the trailer below and let us know what you think.
