In a curious coincidence, this film has two credited Directors of Photography - both of whom would die young. Oliver T. Marsh, the first to be assigned, was a trailblazer among cameramen, considered so talented M-G-M put him under a long-term exclusive contract. Halfway through production of this film, Marsh unexpectedly died of a heart attack at only 49. He was replaced by Sidney Wagner, who would go on to earn multiple Oscar nominations before also dying young, at the age of only 46 in 1947.
The $2,000 that Reginald gave Jonathan would be equivalent to about $39,546 in 2022.
Although the screen credits a play by John Cecil Holm as the basis for the screenplay, no record of any production of the play has been found.
