Cruise is back into the mode of secret spy guy as Roy Miller, a government operative on the lam, accused of going rogue and stealing a valuable energy device. Cameron Diaz is June Havens, one of those movie cliche hot women with a quirky job(she builds classic cars) who can't ever find the right guy. She's about to play second banana at her sister's wedding, and is desperately trying to hop a plane to make it back in time. But she literally keeps bumping into Roy on her way to the terminal, and while this is normally the cutesy setup for a romantic comedy the likes of which these two stars have seen plenty of, in this case all is not as it seems. Or as Roy would say, "Things happen for a reason". Manipulated onto Roy's flight by the people chasing him, June is obviously hot for the mysterious traveller she keeps running into. After some awkward flirting, Roy is forced to fight off an entire plane full of hitmen, and June realizes that the potential man of her dreams might actually be a nightmare.
The question is: Who's side is Roy really on? He's being pursued by his former partner, Agent Fitzgerald(Peter Saarsgard), who wants both the device and the man who created it, Simon Feck(Paul Dano). Roy is determined to protect both, but for what reason? Has he really gone rogue, looking to sell the device to the highest bidder as the government claims? It isn't hard to figure out, really. The script by first time writer Patrick O'Neill doesn't throw any curveballs. It's straight ahead, breezy action from start to finish.
On the surface, Knight and Day has a lot in common with Killers, another star studded spy flick with a gorgeous couple at the forefront. The two approaches taken, however, couldn't be more different. Where that film couldn't decide whether it was comedy or action and does neither successfully, Knight and Day is clear from the start that it's meant to be ridiculously over-the-top.

None of it would've worked if not for the sexy chemistry of Diaz and Cruise. Both actors looking to bounce back, this is the first time I've enjoyed Diaz in any film since Charlie's Angels
The plot is about as generic as they come. Don't even worry about the device Roy is smuggling. It only matters for a second or two at the film's conclusion. Indie faves Sarsgaard, Dano, and Viola Davis aren't really given a lot to work with. But then this isn't really a movie about them. It's about Cruise and Diaz, and that star power is what makes Knight and Day so much fun to watch. I can imagine hating this film with the heat of a thousand suns if it starred Ashton Kutcher and Katherine Heigl. As pretty as Kutcher and Heigl might be, they aren't movie stars. It's been a summer of major disappointment for the most part, but Knight and Day is one blockbuster thrillride that is worth the price of admission.
