Oh! Susanna is a 1951 Republic Pictures Western film directed by Joseph Kane, written by Charles Marquis Warren and starring Rod Cameron, Lorna Gray (billed as Adrian Booth), Forrest Tucker and Chill Wills.
Cavalry officers clash over a saloon singer and an Indian treaty in the gold-rush Dakota Territory.
Parts of the film were shot in Aspen Mirror Lake and Strawberry Valley in Utah.
In a contemporary review for The New York Times, critic A. H. Weiler wrote: "[T]his saga of strife in the Black Hills of the Dakota Territory is what any dime-novel reader might expect. ... This, however, can be said for the adventure. It has about as much conflict as could be wished."
