Showdown is a 1973 American Western film produced and directed by George Seaton and starring Dean Martin, Rock Hudson and Susan Clark.

The seemingly inevitable ending takes a twist that allows the friendship to continue after Billy commits an act of bravery that he knows is suicidal but saves Chuck's life.

It was the final film for Seaton, who three years earlier had directed Martin and an all-star cast in the blockbuster hit Airport.

In a November 1972 episode of the TV series McMillan & Wife called “Cop of the Year,” McMillan (played by Hudson) visits the set of a Western film titled "Showdown" that is in production (directed by Seaton, who plays himself) to ask the special-effects supervisor about how to make a gunshot wound appear on the chest of a gunman—who, in the shot being filmed, is the victim in a showdown.

But along with the pairing of Hudson & Martin, who share the screen for the first time, it’s the films low-key modesty that ends up being one of its most charming features.
