Along the Great Divide is a 1951 American Western starring Kirk Douglas, Virginia Mayo, John Agar and Walter Brennan.

In a 1986 interview with David Letterman, it was one of two movies Kirk told the audience that they "could skip" in his filmography; the other was The Big Trees.

[citation needed] Federal marshal Len Merrick (Kirk Douglas) and his two deputies rescue cattle rustler and murder suspect Tim "Pop" Keith (Walter Brennan) from a lynch mob headed by grieving rancher Ned Roden, whose beloved son was shot in the back.

After he is warned of Roden's intentions by fellow ranchers, Merrick decides to take an unexpected desert route, where he can see if he is being trailed.

The marshal reveals his unswerving devotion to duty is because the one time he neglected to do so it cost his father his life.

Merrick tells the jury he is sure Keith is not a killer, though all the evidence and witnesses are against him where a guilty verdict is reached.

Just before Keith is to be hanged, Merrick notices the watch he found on the body of the dead brother has an inscription to Dan.
