Dialogue makes reference to "Where is Operator 13?" OPERATOR 13 was an MGM Civil War drama released in 1934, costarring Ted Healy. The Stooges were still under contract at MGM, and Curly Howard had a small cameo as a Confederate soldier in that film. Costume and makeup test production stills of Curly in OPERATOR 13 exist, and one can be found in the 2006 Larry Fine biography One Fine Stooge by Steve Cox and Jim Terry.

Opening title music is an arrangement of "Dixie" and "John Brown's Body," by Louis Silvers; see The Three Stooges Journal # 88 (Winter 1998).

UNCIVIL WARRIORS was adapted for the first issue of The Three Stooges comic book series published by Jubilee Publications. Moe's son in-law Norman Maurer served as the comic's editor, writer and illustrater, with his partner Joe Kubert. The issue was released in February 1949. The comic book version is slightly different from its film counterpart, with the Stooges portraying Union spies named Lieutenant Al Mond, Captain Ches Nutt and Major Phil Bert. Moe, Larry and Curly are assigned to infiltrate General Cornligger's headquarters at Confederate Army Camp and liberate Operator 13, who turns out to be an attractive blonde named Miss Draindrop Ansby.
