When Dick flies into her country, he is greeted as a hero by the king (Frank Morgan) and finds Rosalie is engaged to marry Prince Paul (Tom Rutherford), who actually is in love with Brenda (Ilona Massey).

On December 31, 1937, Frank Nugent reviewed the film for The New York Times: “Deploying its formidable phalanxes of talent…in one of the most pretentious demonstrations of sheer mass and weight since the last Navy games, Metro-Goldwyn-Mayer brings forth…"Rosalie"….

Eleanor Powell tap dances… among sets entirely divorced from reality, Nelson Eddy sings as well and as inopportunely as could be imagined, and expensive secondary people…try to compensate with personal mannerisms for all the bright things the dialogue and action fail to say or do… Ray Bolger bolges, sometimes amusingly, sometimes not.

"[6] The reviewer at allmovie.com calls the film an "overproduced musical extravaganza", and noted, "The flimsy plot all but collapses under the weight of Gibbons' enormous sets and dance director David Gould's ditto choreography.

[2][3] MGM's top tap dancer at the time, Eleanor Powell, was cast as the princess opposite Nelson Eddy as cadet Dick Thorpe (Lieutenant Richard Fay in the stage musical).

Also appearing in the film were Ray Bolger (Bill Delroy), Edna May Oliver (the queen), Ilona Massey (Brenda), Tom Rutherford (Prince Paul), and Reginald Owen (Chancellor).
