The first credit frame on this film reads: "Willis Kent presents GUN SMOKE - A Montie Montana Western - Adapted from Gunsmoke Over the Guadalupe by Paul Evans Lehman". This was produced by Willis Kent and Willis Kent only. The reason for the "A Montie Montana Western" credit line was because the film was slated to star Montie Montana, who had starred in Kent's The Circle of Death (1935), but he had to drop out of this film. However, the "honorary" credit line was already on the graphic, and Kent wasn't one to spend money to re-do anything. Consequently, Horse Wrangler / Trainer / Player Rocky Camron / Gene Alsace (billed here as Buck Coburn) got his first--and only--starring role. The pinto, however, did belong to Montana, but he did NOT produce this film, and isn't credited as a producer to begin with.
The saloon set, with stairs leading to a upstairs gallery, was reused in Marihuana (1936) and Gambling with Souls (1936).
