I was sort of influenced by the somewhat bad reviews I had read about this movie, but decided to watch it anyway, because both Tom Cruise and Cameron Diaz usually make good movies. So I sat down and watched it, and I am glad that I did.

There is action all throughout the movie, from the beginning till the very end, and it is the sort of action that is in your face and keeps your adrenalin pumping without being too much over the edge. And the action scenes were well choreographed and worked well.

Also, the comedy in the movie was well used at the right times, adding a lot of flavor to the movie. This aspect gave the movie so much charm and it worked wonderfully. Both Cruise and Diaz were good with these comedy twists.

The story is pretty straight forward and easy to follow, leaving some up for you to guess and speculate about, and that was good.

As for the cast, well as always, Tom Cruise and Cameron Diaz put on magnificent work. I personally think that this is actually one of Tom Cruise's best movies. But of course, we all have our own preferences. The supporting cast also did well.

My friend said that this movie seemed like an imitation of the "Mission Impossible" movies, but I think it is in a whole other league. This one is an action-comedy while the others are pure action.

This movie is good for an evenings entertainment with lots of action and laughs. And the chemistry between Cruise and Diaz makes it worth it just for that alone. If you haven't seen this movie already, get to it!

Although far inferior in both concept and results, "Knight and Day" has its roots in the classic screwball comedies of the 1930's. Cute, seemingly coincidental airport encounters connect an attractive blonde, Cameron Diaz, who is en route to her sister's wedding, with a handsome man of mystery, Tom Cruise, and a series of wildly improbable events ensues. An early scene aboard a near-empty airliner is perhaps the film's highlight, as Cruise does battle with unknown assailants, while a blissfully unaware Diaz primps in the restroom, intent on seducing Cruise. Perhaps if the humor and pace of this scene had been sustained, the film would have been more successful. If Cary Grant were the dashing stranger and Katharine Hepburn the unwitting accomplice, the film would have been classic.

However, while they are attractive leads, Tom Cruise and Cameron Diaz are not Grant and Hepburn. Although the pair have undeniable star power and seem to be having fun, their eyes were likely focused more on the paycheck than on the superficial script which lacks the witty exchanges of classic screwball comedy. Also appearing for the money is a talented supporting cast that includes Viola Davis, Peter Sarsgaard, and Paul Dano; unfortunately, none of these gifted performers have roles that stretch their acting skills. With chases, gunfights, and rapid cutting, director James Mangold keeps the film moving at breakneck speed as the cast chases a "McGuffin" in the form of a super battery, whose importance is often lost in the sometimes confusing proceedings.

Although even the classic screwball comedies stretched credibility, Mangold's film uses CGI to create sequences that are beyond preposterous. At times, Cruise seems to be a super-hero with supernatural powers; his close encounters are unbelievable even for a Batman or Fantastic Four. As the complicated plot unfolds, the characters' motivations seem to shift, and the audience is kept guessing as to who can and cannot be trusted and who is working for whom. The action, light comedy, and appealing performers will hold viewer interest throughout, although, like cotton candy, this fluffy piece will fade from memory before the closing credits finish rolling.

Into the life of Cameron Diaz who hails from Wichita, Kansas and is trying to get to her sister's wedding in Boston and who is the sexiest auto mechanic you'll ever see comes secret agent Tom Cruise. He's got himself an all purpose battery developed by Paul Dano that he's on the run with. Pulling the old Murphy shuffle in the Wichita Airport he puts it in Diaz's luggage. After that her life is in his hands.

I have to say that Diaz for someone who has no training does take to the life of a secret agent on the run quite naturally with Cruise. Of course he's innocent, he stole the battery which will have perpetual energy to keep it from another agent, Peter Sarsgaard, from turning it over to an international arms dealer played by Jordi Molla.

In the space of a few days Diaz and Cruise are all over the globe, Wichita, Boston, Salzberg, Spain, and even a nice tropical island for a brief respite which is rudely interrupted. The plot is reminiscent of the Cary Grant/Audrey Hepburn classic Charade which is not quite as action packed, but has the same premise of Hepburn never quite sure if she can trust the charming Grant.

No one will ever list this as one of Tom Cruise's best films, but his international star brigade will be pleased.
