This was W.C. Fields's last filmed appearance. He had supported the war effort, but his health was declining. His billiards routine (using a trick table) was a crowd pleaser.

Decca Records star Bing Crosby, who did not appear in this film, combined with The Andrews Sisters on two "Billboard"-charting songs featured in the score: "Vic'try Polka" (music by Jule Styne, lyrics by Sammy Cahn), sung in the picture at the conclusion of a greatest-hits medley by 'The Andrews Sisters, a number-five "Billboard" tune in 1943; and "Is You Is or Is You Ain't (Ma' Baby)" (music and lyrics by Louis Jordan and Billy Austin (I)), performed in the movie by Mr. Jordan singing with his orchestra, a number-two "Billboard" ditty for Crosby and the trio in 1944. On their own, the Andrews Sisters waxed for Decca and then repeated in this film a jivey song of farewell, "Shoo-Shoo" Baby" (music and lyrics by Phil Moore). Between late December 1943 and mid-April 1944, the sisters' 78 ranked as high as #3 among the "Billboard"-charting singles. Placing alongside was the Ella Mae Morse cut of "Shoo-Shoo Baby" on Capitol. In another musical from Universal, South of Dixie (1944), Ella gave out with her rendition.
