Exclusive: Jack Reacher trailer premiere

It has been a tumultuous week for Tom Cruise. First he was hit with divorce papers… then he turned 50! We're not sure what's more depressing.

It's enough to make you forget he's also a major movie star with several huge projects coming up, including this film version of insanely popular Jack Reacher books, written by Lee Child.

Check out the EXCLUSIVE first trailer below.

Some of you may remember there was a minor online backlash when Cruise was cast, with fans complaining he was "too small". They have a point, as the maverick homicide cop is supposed to be 6'5" in the books, but Child himself said he was "thrilled" about Cruise's casting.

And if there's one thing the newly-single star does better than anyone, it's beating up baddies, as this action-packed trailer proves.

Christopher McQuarrie, who also directed Cruise in 'Valkyrie', is behind the camera while Rosamund Pike, Robert Duvall and intriguingly Werner Herzog co-star.

'Jack Reacher' is released on 28 December 2012.
