About working with Rod Steiger, Glenn Ford said, "Rod . . . well, in kindness I think I should say he did a great job with his role. However, the 'Method' got a little too much for some of us, especially the wranglers . . . Look, Rod won an Academy Award, didn't he? And so did Ernie [Ernest Borgnine], so whatever Rod was doing in his role for 'Jubal' probably worked for him. He was intense, I'll tell you that."
Very loosely inspired by William Shakespeare's "Othello"--Shep corresponds to Othello, Pinky to Iago and Jubal to Cassio. Naomi's gift of a handkerchief echoes a similar gift from Bianca, but is not used further as a plot device
