Hollywood Reporter news items, as well as Daily Variety and Hollywood Reporter production charts, include Samuel S. Hinds in the cast, but he did not appear in the released film. According to modern sources, Hinds was originally cast in the role of "Dr. Carroll." Modern sources also state that the film was originally written for the Ritz Brothers, and that little in the original script was changed, even though their roles were eventually played by actresses Grace McDonald, Betty Kean and June Preisser. Modern sources credit Mort Singer, Jr as assistant director. Universal made two earlier film versions of Erich Philippi's screenplay. The first was released in 1933 as Secret of the Blue Room, starring Lionel Atwill and Gloria Stuart and directed by Kurt Neumann, while the second was released in 1938 as The Missing Guest, starring Paul Kelly and Constance Moore and directed by John Rawlins (see AFI Catalog of Feature Films, 1931-40; F3.2909 and F3.3946).
