Knight & Day

What's the story: We know Hollywood loves remakes, but was it really necessary to take another swing at Killers so soon after its failure at the box office? For those who haven't put on a television, turned on a computer or read a newspaper in the last month, Knight & Day finds Tom Cruise — and his toothy grin — starring as Ray Miller, a rogue C.I.A. agent who becomes infatuated with civilian named June Havens (Cameron Diaz, also heavily featuring her best Colgate smile) while trying to avoid explosions. There are double crosses — hey, Peter Sarsgaard, we hope Knight & Day bought you and Maggie Gyllenhaal the finest organic groceries Park Slope has to offer — and preposterous stunts, but in the end, this is The Tom Cruise Show. And based on the initial box office — Knight & Day opened on Wednesday to just $3.8 million, the lowest opening day for a major film starring Tom Cruise since Far and Away — audiences have long since changed the channel. Critics have too — though our Sara Vilkomerson found Knight & Day to be "straight-up fun, hiding nothing about its intentions" — but for the sake of Twentieth Century Fox's marketing department, maybe go buy a ticket to see Knight & Day. After all the work they put in, they deserve your help.

Who should see it: Mr. & Mrs. Smith.

Grown Ups

What's the story: Another week, another worst movie of the summer. This time around, it's Grown Ups that gets to take a turn in the barrel. Basically a Happy Madison version of The Big Chill, Adam Sandler's latest just seems like an excuse for the mumbling superstar to hang out with his friends — Rob Schneider, David Spade, Chris Rock, Kevin James, and director Dennis Dugan. The reviews have been toxic — with some going as far to say that this is the worst movie of Sandler's career. And this is the guy who made Waterboy. And Little Nicky. Abandon all hope ye who enter here.

Who should see it: Lorne Michaels.

Also opening this weekend: Wait, there's a good movie coming out today too? Stop the presses! Restrepo — about Sebastian Junger and Tim Hetherington being embedded with a platoon of Marines in Afghanistan — won the Grand Jury Prize at Sundance for documentaries, and will probably be more worth your time than seeing Grown Ups. Just guessing.
