In the opening credits Louis Armstrong and His Orchestra are included in the cast, above "Guest Stars" Vic Damone and Monica Lewis, but Armstrong is not included in the end credits. Pete Rugolo, who is credited with Leo Arnaud with the film's orchestrations, was a well-known jazz arranger. As noted in a voice-over narration, the area of Los Angeles known as the "Sunset Strip" was an unincorporated part of Los Angeles county that surrounded Sunset Blvd., west of Hollywood and east of Beverly Hills. Because the area was not part of the city of Los Angeles, it was policed by the L.A. County Sheriff's Department. In 1984, Sunset Blvd. and surrounding areas were incorporated into the new city of West Hollywood. According to Hollywood Reporter news items, and confirmed by the film, much of the picture was shot on location in and around the Sunset Strip. Interiors were shot at popular nightclubs Mocambo and Ciro's and at restaurants Little Hungary and Stripps. A news item in the Los Angeles Evening Herald and Express noted that the "La Bota" number, featuring Marcia Lewis, was filmed inside Ciro's.
According to Hollywood Reporter news items, Bob Spencer, Helen Spring, Michael Dugan and Eddie Polo were in the cast, but their appearance in the released film has not been verified. A May 31, 1951 Hollywood Reporter "Rambling Reporter" column indicated that Sammy Gordon was planning to sue M-G-M, which used his nightclub for interiors of the film, but failed to show the exterior, as promised, even though "every other place on the Strip had their names prominently displayed."
In addition to the numbers performed in the released film, jazz instrumentals that were recorded by Louis Armstrong but cut from the production included "Ain't Misbehavin'" by Fats Waller and Harry Brooks, "One O'Clock Jump" by Count Basie and "I'm Coming, Virginia" by Donald Heywood. Those numbers, plus several songs from the film were included in the CD-anthology album "Now You Has Jazz: Louis Armstrong at M-G-M," released in 1997. "A Kiss to Build a Dream On" was nominated for an Academy Award for Best Song, but "In the Cool, Cool, Cool of the Evening," from the Paramount film Here Comes the Groom won the award.
