Much of this film was shot at the famous "Old Tucson" facility, not far from the real Tombstone. However, its "town street" set was used surprisingly as Fort Griffin, Texas, in the opening reels, while later Tombstone street scenes were shot in southern California, on the same Paramount Ranch set that was later used as Virginia City, Nevada, on TV's "Bonanza" (1959).
Dennis Hopper, who plays Billy Clanton, was actually born and raised in Dodge City, Kansas.
The actual gunfight took place on 26 October 1881 and lasted a mere 30 seconds, resulting in three dead men after an exchange of 34 bullets. Compared to this adaptation, the movie gunfight took 4 days to film and produced an on-screen bloodbath that lasted 5 minutes.
In July 1957, this film was released to many drive-in theaters on a double bill with Destination 60,000 (1957).
