Dinah Shore had to sing Ethel Merman's songs on the original cast album for the Broadway play because Merman, who had starred in the original stage production, was under contract to Decca Records, who wouldn't release her to do the album.

Ethel Merman recreated the role that she had originated in the Broadway production which opened at the Imperial Theatre on October 12, 1950 and ran for 644 performances through May 3, 1952.

Ethel Merman's on-screen rendition of "The Hostess With the Mostes' on the Ball" was shorter than her Broadway version, which had included an encore, and a stage quip warning an ambassador's date "not to leave her panties in the hall" was scrubbed from the picture's lyrics.

A lesser-known 'Irving Berlin (I)' ballad from his 1950 stage score went missing from the film: "Once Upon a Time Today," written for the Kenneth Gibson character and performed on Broadway by Russell Nype.

Before pre-recording the song "You're Just in Love", Donald O'Connor felt that a better result would be achieved if he sang it with Ethel Merman in a recording studio accompanied by the orchestra. Musical Director Alfred Newman agreed and let them sing together. It turned out that Merman's legendary loud singing voice was too deafening for O'Connor. In the end, they had to record the song with O'Connor in an isolation booth. When filming the musical number accompanied by the pre-recorded playback, O'Connor had to wear ear plugs.

Due to the expiration of 20th Century Fox's music rights, the movie was completely withdrawn from public exhibition (both TV and theatrical) for nearly 20 years. During that time, its only public showing (with special permission from Irving Berlin) was at a 100 year tribute at the Los Angeles County Museum of Art in the 1990s. After the rights were renewed, the film was finally released on DVD in April 2004.

For the 1950-51 Broadway season, Ethel Merman's performance in "Call Me Madam" won the Tony Award for Leading Actress in a Musical.

In all but one scene in this movie Vera-Ellen's neck is covered. She suffered from anorexia and her neck and throat were thin and wrinkled.

Instead of loaning out Ethel Merman to RCA Victor for the original-cast album of "Call Me Madam" (Dinah Shore replaced her), Decca made their own album with Merman, Dick Haymes and Eileen Wilson. On it, Merman sings the song "Washington Square Dance," which is heard in the movie only as background music in the opening party scene in Washington, D.C.

Lichtenburg is actually a fictionalized name for Luxembourg. The character of Sally Adams is based on the real-life Perle Mesta (although the plot of the film is entirely fictional), and Perle Mesta was named Ambassador to Luxembourg by President Truman.

One of the few major musical films of the 1950's which was never shown on one of the 'Big Three' networks, ABC, NBC, or CBS. It was, instead, sold directly to local stations, as most films used to be prior to 1956.

The movie contains two vintage Irving Berlin songs written before his 1950 Broadway score. "The International Rag" (as Ethel Merman sings it, although the official title is "That International Rag") had been introduced by Mr. Berlin himself at the London Hippodrome in 1913. Sophie Tucker made the ditty famous via her vaudeville act. In the picture, just prior to delivering this number at the presentation ball, Ethel jokes with the orchestra leader (played by Leon Belasco) about this "hot" new tune from 40 years earlier. Donald O'Connor's song-and-dance-solo, which had him tearing up a tavern -- "What Chance Have I With Love?" -- was first performed by Victor Moore in Irving Berlin's 1940 Broadway musical, "Louisiana Purchase." Although Mr. Moore would appear in Paramount's 1941 screen adaptation, his lament to love would not carry over to this film score.

The pairing of Donald O'Connor and Vera-Ellen was very well received, due to their complementary dancing styles and personalities. However, attempts to re-team them were unsuccessful, most notably with White Christmas, in which Danny Kaye replaced O'Connor at the last minute due to his sudden and severe illness. Coincidentally, Danny Kaye is mentioned in "Call Me Madam" as a joke.

The stage production of "Call Me Madam" opened at the Imperial Theater in New York on October 12, 1950 starring Ethel Merman and ran for 644 performances.

This is the only full film musical that George Sanders made, despite his appealing singing voice.

Two Irving Berlin musical satires of Washington D.C. politics were not transferred from Broadway to Hollywood: the Ethel Merman-centered "Washington Square Dance" (although in the movie a few bars are sung by an off-screen chorus, and the melody is played during a party scene); plus a trio of senators (who on Broadway were Pat Harrington Sr., Ralph W. Chambers and Jay Velie) intoning "They Like Ike" (which inspired the memorable catch phrase of the 1952 Eisenhower presidential campaign).

What had been an Ethel Merman number on Broadway, "Something to Dance About" was filmed with Donald O'Connor and Vera-Ellen (dubbed by Carol Richards) singing and dancing in a secret passageway. Along with George Sanders, the aforementioned all reprised a bit of this tune in the final medley, which also included "You're Just in Love."

While Donald O'Connor was hesitant to select a favorite film, he was quick to single out his favorite performance: "Call Me Madam - my favorite number is in there with Vera-Ellen. It's the number I do out in the garden with her to "It's a Lovely Day Today". It's a beautiful lyrical number. I think she was the best dancer outside of Peggy Ryan I ever danced with".

While Alfred Newman took home the Oscar for Scoring of a Musical Picture, he had failed to garner a nomination that same year in the dramatic category for The Robe, a score considered by film-music scholars to be one of Mr. Newman's finest compositions.
