"The Screen Guild Theater" broadcast a 30 minute radio adaptation of the movie on May 8, 1944 with Merle Oberon reprising her film role.
Herbert Marshall, who plays a British army officer in World War I, actually served in that war and lost a leg in combat.
Lux Radio Theatre version starring Merle Oberon, Herbert Marshall, and Rod La Rocque aired June 22, 1936. In the radio version, Marshall played the role of Alan Trent instead of his film role of Gerald Shannon.
The play opened on Broadway in New York City on 10 February 1925 and closed in April 1925 after 63 performances. The opening night cast included Claud Allister, who is also in the film. The playbill listed Guy Bolton's alternate name, "H.B. Trevelyan," as the author.
The role of Alan Trent was originally intended for Leslie Howard, who was having an affair with Merle Oberon at the time. When the affair ended, Howard dropped out of the production and Fredric March replaced him - much to the disgust of director Sidney Franklin, who thought Oberon wouldn't draw audiences without Howard as her co-star.
