The theme for Betty Grable and her husband the forest ranger was "You'll Never Know" (music was written by Harry Warren and the lyrics by Mack Gordon) which was introduces by Alice Faye in the movie Hello Frisco, Hello (1943) and it won the Oscar (R) for the Best Song. Betty Grable replaced Alice Faye as 20th Entury Fox's blonde comedy star. In this picture Marilyn Monroe became their blonde comedy star surpassing Betty.
Lauren Bacall's character, Schatze, says, "I've always liked older men... Look at that old fellow what's-his-name in The African Queen (1951). Absolutely crazy about him." She is referring to Bacall's real-life husband, Humphrey Bogart.
Towards the end of the movie where Shatze is talking to J.D. Hanley and she says "... and who does he think he is anyway" the shadow of some lighting equipment can be seen on the painting near the mirror.
