Starring: James Arness, Ken Curtis, Amanda Blake, Milburn Stone
Factual error: In the opening dialogue by Matt Dillon on Boot Hill, the last shot of a tombstone has the date of 1982.
Suggested correction: It's not a "9" but an "8." The two 8's don't really match, but you can see the other tombstone with a similar "8." It's 1882.
Continuity mistake: Marshall Dillon buries an outlaw at Sarah's place. He installs a wood cross at the grave. Sarah comes out and they talk. When she leaves, the scene cuts back to Dillon and the cross is missing.
Dr. Galen 'Doc' Adams: I'll tell you why the Hagens live so long.
Festus Haggen: Why?
Dr. Galen 'Doc' Adams: 'Cause they're too dumb to know they're dead.
Trivia: Although they played father and son in this episode, Jack Elam was only six years older than Harry Dean Stanton.
