Will Penny is a 1968 American Western film written and directed by Tom Gries and starring Charlton Heston, Joan Hackett and Donald Pleasence.

The picture was based upon an episode of the 1960 Sam Peckinpah television series The Westerner starring Brian Keith called "Line Camp," also written and directed by Tom Gries.

Will trades his position riding on the train with the cattle to a young cowboy who wants to visit his dying father and tells Will there may be work at the Flat Iron ranch.

Dutchy accidentally wounds himself in the exchange, so the trio head out to find a doctor and first come to a nearby trail store, where they encounter Catherine Allen and her son Horace.

Will and Blue return to attack the cabin to free Catherine and Horace, using a bag of sulfur in the chimney to smoke out the rawhiders and then shoot them all.

With the rawhiders dead the Flat Iron trail boss arrives, Will realizes that he is too old and set in his ways to settle down into a domestic life with Catherine, against her protestations.

The film features a David Raksin and Robert Wells song "The Lonely Rider" with vocals by Don Cherry.

These are the kind of people, we feel, who must really have inhabited the West: common, direct, painfully shy in social situations and very honest."
