Modern sources state that Helen Hayes replaced Norma Shearer in the lead after Shearer decided to stay at home and nurse her husband, Irving Thalberg, who had suffered a serious heart attack.
The early years of talkies relied heavily upon stage adaptations of Broadway plays. Although it would later become common practice to replace Broadway stars, no matter how regarded, with established movie stars, during the dawn of sound many stage performances were captured on film because few film actors were capable of intricate dialogue. In the case of Another Language (1933), four members of the original Broadway cast---Irene Cattell, John Beal, Margaret Hamilton and Hal K. Dawson---reprised their roles for the film version.
Another Language (1933) was the last film for Louise Closser Hale who died two days before this film's release. She had worked on Dinner at Eight (1933) previously, but it was released after this film. And, she had an uncredited part in Duck Soup (1933) that was in production around the time of this film.
"Theater Guild on the Air" broadcast a 60-minute radio adaptation of the movie on January 15, 1950 with Helen Hayes reprising her film role.
