Tom Selleck, Catherine O'Hara and Martin Mull have climbed on board the Lionsgate action comedy Five Killers, starring Ashton Kutcher and Katherine Heigl.

According to Variety, the project will be directed by Robert Luketic (21).

The story follows a hitman (Kutcher) at the top of his game who falls for a computer tech (Heigl) and decides to hang up his guns. Years later, their suburban bliss is ruptured when he finds out there's a hit out on him, forcing him and his spooked wife to go on the run.

Selleck and O'Hara will play Heigl's overprotective father and adoring mother. Mull will play Holbrook, Kutcher's handler.

Bob DeRosa wrote the original screenplay, with additional work by Ted Griffin.

Filming starts this month in France and Atlanta for a June 4, 2010, release.
