Starring the inimitable team of Nelson Eddy and Jeannette MacDonald, along with James Stewart and David Niven in smaller roles, this definitive screen adaptation of Rudolf Friml's popular operetta tells the story of an opera singer who goes undercover in the Canadian wilderness to help her criminal brother and ends up falling in love with the Mountie who captures him. Songs "Rose Marie" and "Indian Love Call" are featured. Shot outdoors in Lake Tahoe, California, the lavish production features over 700 Indians from 50 different tribes.
