“Cromwell’s direction is excellent. […] Colman has the ability to make a full dress court uniform appear as comfortable as a suit of pajamas.” Vgl. The Prisoner of Zenda. In: Variety, 1937.

“One of Hollywood’s most entertaining adventure stories of any era is a triumph of swashbuckling swordplay, careful direction, and reliably professional acting. Ronald Colman and Douglas Fairbanks Jr. are at their best […]. Costuming, photography, and sword-fight choreography are all top-notch under the direction of John Cromwell. Hope’s story had been filmed twice before […], and there would be two later versions; but critics agree that this is the best rendering.” Michael Betzold: The Prisoner of Zenda (Memento vom 8.
