Mr. & Mrs. Smith (2005)
After five (or six) years of vanilla-wedded bliss, ordinary suburbanites John and Jane Smith are stuck in a huge rut. Unbeknownst to each other, they are both coolly lethal, highly-paid assassins working for rival organisations. When they discover they're each other's next target, their secret lives collide in a spicy, explosive mix of wicked comedy, pent-up passion, nonstop action and high-tech weaponry. assassin, bomb, hitman, marriage crisis, gun, secret identity, married couple, assault rifle, marriage, decoy, secret agent, dysfunctional marriage, gunfight, bullet wound, excited, ridiculous
