After breaking up with her boyfriend, uptight Jen Kornfeldt (Katherine Heigl) heads to Nice with her parents (Tom Selleck and Catherine O'Hara) for a holiday. Meeting suave and shirtless Spencer Aimes (Ashton Kutcher) in the hotel lift, Jen is instantly smitten and accepts a dinner date. Three years later and the couple are married and living in suburban bliss, although Spencer has failed to disclose a very important secret about his past. A former government hitman, Aimes is now the target of a contract himself, and, worst of all, the assassins are posing as kindly neighbours. As bullets start flying, and Spencer starts exhibiting some disconcertingly deadly skills, straight-laced Jen realises that if she's going to hang onto her man, she's going to have to learn to shoot back.
Playing out like a particularly ditzy version of Mr. & Mrs. Smith, this critically mauled action comedy may not have an ounce of originality, but it should satisfy those looking for some throwaway entertainment. While the easy-on-the-eye pairing of Kutcher and Heigl may be no match for Brangelina, their negligible chemistry suffices, bantering their way through the reassuringly predictable action sequences with aplomb.
While O'Hara is somewhat underused as Jen's boozy mum, it's Selleck who comes off best as the clandestine dad, helping to make Killers an amiable enough crowd-pleaser.
