Saw Killers some time back and I think the trailer had the funny bits featured in the movie.
Jen visits France with her parents after a breakup and meets Spencer, with whom she falls in love and marries. Unknown to Jen, Spencer is a contract killer but has retired after he met Jen. Fast forward to three years later, they are happily married and living in suburbia. However, Spencer receives a letter from his former boss and soon he realizes that he has a bounty of $2 million on his head, and his colleagues, friends and neighbours are all coming after him.
The only funny part I remembered came from the trailer, where Jen was trying to conceal the gun under the trenchcoat. Even the ending is a little weird – when the guy who called the bounty on Spencer was revealed. Maybe the only thing worth looking out for is Katherine Heigl’s wardrobe and Ashton Kutcher’s hot bod. Look out for a cameo by Usher.
