Lionsgate has debuted the trailer for Killers, an action comedy starring Ashton Kutcher and Katherine Heigl set for release this summer.  The basics: Heigl plays Jen, a computer tech vacationing in Europe where she encounters a shirtless and mysterious Spencer (Kutcher).  As romance ensues, Jen gets caught up in the dangerous world of Spencer who is, naturally, a "government-hired super assassin."  Heigl is re-teaming with The Ugly Truth director Robert Luketic for the feature, which also co-stars Tom Selleck, Catherine O'Hara, and Martin Mull.

Check out the trailer after the break.

The footage treads awfully similar ground to that of Knight and Day, another film centering on lovely female civilian (Cameron Diaz)  whose world is overtaken by a gun-toting "man of mystery" (Cruise).  Both films are vying for blockbuster status this summer.  Killers has the benefit of June release, one month prior to when Knight will hit screens.  But Killers suffers from an incredibly generic title, while Knight and Day may be able to find success due to its gloriously inane (but memorable) moniker.

I've seen many instances of charm emanating from a Heigl performance--evidenced here with the trailer-capping banter about the difficulty of concealing firearms--but I don't know that Killers will feature many more.  If Heigl puts on a good show, and Kutcher's inherent obnoxiousness is counterbalanced by Selleck's inherent coolness, Killers could be fun.

Killers will hit theaters on June 4, 2010.

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

Spencer Aimes is just your average, undercover, government-hired super-assassin accustomed to a life of exotic European locales, flashy sports cars and even flashier women. But when he meets Jen Kornfeldt, a beautiful, fun-loving computer tech recovering from a bad break-up, he finds true love and happily trades international intrigue for domestic bliss.Three years later, Spencer and Jen are still enjoying a picture-perfect marriage... that is, until the morning after Spencer's 30th birthday. That's when Spencer and Jen learn he's the target of a multi-million dollar hit. Even worse, the hired killers have been stalking the happy couple for years, and could be anyone: friends, neighbors, the grocery store clerk, even that crabby old guy shuffling across the street. Now Spencer and Jen are on the run for their lives. As their suburban paradise turns into a paranoid game of dodge-the-bullet, they must find out who wants Spencer dead and why, all the while trying to save their marriage, manage his pain-in-the-ass in-laws, keep up neighborly appearances and just plain survive. And you thought suburban life was easy.
