Mr. and Mrs. Smith (Unrated) (2005)

After five (or six) years of vanilla-wedded bliss, ordinary suburbanites John and Jane Smith are stuck in a rut the size of the Grand Canyon...until the truth comes out! Unbeknownst to each other, they are both lethal assassins working for rival organizations.

And when they discover they're each other's next target, their secret lives collide in an explosive mix of wicked comedy, pent-up passion, nonstop action and high-tech weaponry that gives an all-new meaning to "Till death do us part!"
