Mr. & Mrs. Smith (2005) Unrated

John and Jane Smith are a normal married couple, living a normal life in a normal suburb, working normal jobs…well, if you can call secretly being assassins "normal". But neither Jane nor John knows about their spouse's secret, until they are surprised to find each other as targets! But on their quest to kill each other, they learn a lot more about each other than they ever did in five (or six) years of marriage.
John and Jane Smith are a married couple, both living unexciting lives and attending marriage therapy, as their passion has cooled since they got married. But what they don't know about each other is that they are both professional assassins working for two rival agencies. John's latest assignment is to eliminate Benjaiman "Tank" Danz, but it all becomes complicated when Jane is also assigned to eliminate the same target. Learning that they are both assassins and failing to eliminate Danz, John and Jane's separate employers decide that they try to take each other out (John kill Jane, Jane kill John). Engaged in a deadly game, John and Jane try to take each other out and learns more about each other as they try to finish the job and eliminate Danz.
