Joan Crawford was given complete freedom, without guidance or supervision, to develop her own makeup, hair, and costumes for the film.
This film marked Joan Crawford's return to MGM after a ten-year absence. She was previously under contract to MGM from 1925-1943.
The movie was filmed in 24 days.
In the song-and-dance number "Two-Faced Woman" (music by Arthur Schwartz, lyrics by Howard Dietz), Joan Crawford performs in blackface. Crawford's singing voice was dubbed by India Adams, whose pre-recording was originally intended for Cyd Charisse in The Band Wagon (1953). The song-and-dance performance by Charisse - with Oscar Levant on piano - was dropped from the film. However, the footage appears on the DVD release from Warner Home Video. In That's Entertainment! III (1994), the Charisse and Crawford versions are compared via split screen.
MGM's ad campaign for the film erroneously boasted that this was moviegoers' first chance to see Joan Crawford in Technicolor. However, Crawford had appeared in a Technicolor sequence in MGM's The Ice Follies of 1939 (1939), as well as a guest appearance in It's a Great Feeling (1949) for Warner Bros. Other Crawford films that contain color sequences in which she appears are The Hollywood Revue of 1929 (1929) and The Women (1939).
