Jubal could just as easily have been titled Othello Out West, even though it was officially based on a novel by Paul I. Wellman. The Othello counterpart is likable (and extremely gullible) ranch owner Shep Horgan (Ernest Borgnine). Horgan hires handsome drifter Cassioer, Jubal Troop (Glenn Ford) as a cowhand, much to the delight of the film's "Desdemona", Horgan's hedonistic wife Mae (Valerie French). The "Iago" of the proceedings is psychotic ranch hand Pinky (Rod Steiger), who, envious of Jubal and hoping to enjoy Mae's sexual favors, sows the seeds of suspicion in Horgan's mind by falsely accusing Jubal of messing around with Horgan's wife. Amidst all this nastiness, there is at least one wholly virtuous character, pretty Naomi Hoktor (Felicia Farr), so guess who Jubal eventually winds up with?
