Mr. & Mrs. Smith (2005)

Mr. & Mrs. Smith is a 2005 American action comedy film directed by Doug Liman and written by Simon Kinberg. The film stars Brad Pitt and Angelina Jolie as a bored upper-middle class married couple surprised to learn that they are both assassins hired by competing agencies to kill each other.

Besides being a box office hit, it is also notable for establishing Jolie and Pitt's relationship.^[1][2]

The film opens with construction executive John (Brad Pitt) and tech support consultant Jane Smith (Angelina Jolie) answering questions during marriage counselling. The couple has been married for "five or six" years, but their marriage is suffering to the point that they cannot remember the last time they had sex. They tell the story of their first meeting in Bogotá, Colombia, where they were both secretly on the run from the Colombian authorities - since the authorities were looking for tourists travelling alone after a recent heist, the two claimed to be together to avoid being questioned. They quickly fell in love and married. John later states that Jane "looked like Christmas morning" to him on the day they met.

In reality, John and Jane are both skilled contract killers working for different firms, both among the best in their field, each concealing their true professions from one another. The couple live in a large Colonial Revivalhouse in the suburbs and, to keep up appearances, socialise with their "conventionally" wealthy (and disliked by each Smith) neighbors.

Under these cover stories, John and Jane balance their apparently mundane marriage – which both of them find after a few years to be growing dull and suffocating – with their secretive work. When both are assigned to kill DIA prisoner Benjamin "The Tank" Danz (Adam Brody) during a transfer, they encounter each other on the job and the hit ends up botched. Each is then assigned to eliminate the other.

After making escalating attempts on each other's lives, the Smiths' conflict culminates in a massive shootout that nearly demolishes their home. In a protracted, evenly matched fight, they wind up with guns in each other's faces. John declines to shoot, his feelings for Jane rekindled, and lays his gun down. Jane finds she cannot shoot John either, and the two have passionate sex.

The renewed Smith partnership is quickly threatened by their employers, who join forces to eliminate the couple. John's best friend and coworker, Eddie (Vince Vaughn), turns down a bounty of $400,000 for each Smith (since he won't get out of bed for anything less than $500,000), but John and Jane find themselves under fire from an army of assassins. Fending off an attack which blows up their pockmarked house, the Smiths steal their neighbor's minivan and successfully destroy their attackers' three pursuing armored sedans, all while bickering over their fighting styles and newly discovered personal secrets.

After meeting with Eddie, the Smiths decide to fight together to preserve their marriage. They kidnap Danz from his high-security prison in order to use him as a bargaining chip. Danz reveals that he was merely bait, hired jointly by their employers after it was discovered that the Smiths were married, in the hopes of having one Smith kill the other. John and Jane forgo their separate contingency plans and make their stand together. In the final fight scene of the film, the Smiths – now working smoothly together as a team – defeat an extended attack by a large force of armed personnel during a long shootout inside a department store.

The film ends with the couple meeting the marriage counselor (William Fichtner) again, where the Smiths state how much their marriage has thrived, with John encouraging him to ask for an update on their sex lives (to which he silently answers "10").

An alternate ending shows that they chose to move to another country and had a child who inherited their assassin skills.
