My Darling Clementine

The cantankerous Walter Brennan disliked John Ford so much that he never worked with him again. One time when Brennan was having trouble getting into the saddle, Ford yelled, "Can't you even mount a horse?" Brennan shot back, "No, but I got three Oscars for acting!"

The movie shows James Earp killed (murdered) with his marker showing "born 1864 died 1882". However, James Earp was in fact born in 1841 and died in 1926 of natural causes. It was Morgan Earp who was murdered on 18 March 1882.

In 1994, an alternate "preview" version of the film was found that runs 103 or 104 minutes, according to different sources. In June 1946, director John Ford showed producer Darryl F. Zanuck his cut of the film. Zanuck's opinion was that the film had some problems, so Zanuck reshot certain scenes with Director Lloyd Bacon. Zanuck also recut other scenes, changed the music at certain points, and slightly altered the finale. In all, 35 minutes of footage was shot or recut, and the film was released at 97 minutes. Both the 103-104 min. archival preview print and the 97 min. release print are on the Fox DVD released January 6, 2004.
