Previously known as "Witchita" and once known as "Trouble Man", the upcoming Tom Cruise/Cameron Diaz film will now be titled "Knight and Day", which sounds like a title Kenneth the Page would come up with when pitching a sitcom about a medieval knight transported to modern times and falling in love with a woman with the last name "Day".  Hit the jump for details on the film and why its potential success may have little to do with its lead actors.

15 years ago, Tom Cruise and Cameron Diaz, would have been able to make this an easy summer blockbuster.  It was only eight years ago when they opened "Vanilla Sky" to a $25 million opening weekend even though it's an almost shot-for-shot remake of the mindfucking Spanish film, "Abre Los Ojos".  But 15 years ago, people didn't think Tom Cruise had gone off the deep end and Cameron Diaz wasn't pushing 40 but playing roles intended for 25-year-olds (although more power to her for that).

But that doesn't mean either one can't act because they can and it doesn't mean "Knight and Day" will be bad, although director James Mangold didn't wow me with "3:10 to Yuma" or "Walk the Line".  The movie has strong supporting actors like Peter Sarsgaard, Viola Davis, and Paul Dano around and it has a solid premise so I'm staying interested in this project, at least for now.

For those just tuning in, here's a brief synopsis:

Tom Cruise plays a man of mystery who links up with Diaz. They become fugitives, there are betrayals and shifting alliances all around them, and they must figure out whether to be guided by the truth or trust in one another.
