Mr. & Mrs. Smith

Starring "Brad Pitt" as John Smith and "Angelina Jolie" as Jane Smith the movie was released in 2005 and was a major hit.
John is a secret agent and so is Jane but in different organizations with same assignments but different motives. They meet in Columbia and after a love affair get married. The story of the movie goes on sideways with John and Jane talking about themselves to a marriage counsellor. Everything goes fine until one day when both come to know about each other. They shoot bullets at each other, throw knives to kill each other, but then they find out some one wants to kill them both. They rejoin and rest is history.
The movie with great latino music along with great action sequences is a must watch.
