It's like Night and Day

Ever wonder why Tom Cruise is a movie star? Do you stop and pause to consider if there is more to Cameron Diaz than her looks? If yes, then let me refer you to the trailer for KNIGHT & DAY.

In the trailer you see the sparkle in Tom Cruise's eye that makes him a movie star. That easy grin that allows him to do the impossible and command a giant screen and our attention. It's all there, in a combination of RISKY BUSINESS and MISSION IMPOSSIBLE, with a heavy dose of the humor he exhibited when working with Ben Stiller for an MTV spot many years ago.
Cameron Diaz also rekindles flames that seemed to have burned out long ago. After phoning it in for years now, whether as Princess Fiona or some sex kitten, she finally seems to be having fun on screen.
This combination should lead to a box office hit. I don't know what this movie is about, but it looks like fun.
