Hunted killer Robert Miller Barr--whose companion was lynched in Yreka, California, the year before for killing two cops while he himself escaped--got a job as an extra in this movie while on the run. He appears in eight scenes. See "The Spokesman-Review", Sept 16, 1936.
Many reference books erroneously state that this film was shot in Jasper, Alberta, Canada. In fact, it was the remake of this movie, Rose Marie (1954), that was partially shot in Canada.
MGM's original intention was to film in Technicolor and to star Grace Moore. If these plans had gone through, this would have been MGM's first feature-length Technicolor film. However, Moore decided to pass on the film, Jeanette MacDonald was cast, photography switched to black-and-white, and this film became one of the biggest musical successes in MGM's history.
Adapted from a Broadway play that opened on September 2, 1924, at the Imperial Theatre in New York and ran for 557 performances.
As publicity for this movie, MGM offered $2,000 to the first woman that year to name their twin daughters Rose and Marie. The prize went to Mrs. Esker R. Owens of Fort Smith, Arkansas.
