 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 TVs _"Bonanza" (1959)_ (qv).
