Although onscreen sources credit Dr. Donald MacKenzie as the film's recording director, most contemporary sources credit noted sound man Frank MacKenzie with sound. It is probable that the onscreen credits were incorrect. Although the cast credits at the end of the film list actress Zelda Sears's character as "Mrs. Otto Drukker," within the film she is referred to as the sister of "Adolph Drukker." As noted in reviews, the story's various murders were staged to be suggestive of popular nursery rhymes such as "Humpty Dumpty."
Modern sources add Richard Cramer and Broderick O'Farrell to the cast. The Bishop Murder Case was the only film in which Basil Rathbone portrayed the popular S. S. Van Dine detective, "Philo Vance."
