Joan Crawford does a cameo and directs a short speech to Jack Carson before slapping his face. It's the same one she gives to Ann Blyth in Il romanzo di Mildred (1945) before slapping her face. Carson co-starred in that film with Crawford.
Patricia Neal, still wearing the black fur-trimmed evening gown from La fonte meravigliosa (1949) came directly from that set to film her ballroom scene cameo.
Doris Day did not consider this film as much of a picture, but she enjoyed the role of a movie actress and it came naturally to her. She also liked the regular hours of the studio, compared to the late night hours she had spent on the bandstand for several years.
This film has cameo appearances from three great directors of the era: Raoul Walsh, King Vidor, and Michael Curtiz.
Jack Carson and Dennis Morgan were being groomed as Warners' answer to Paramount's popular comedy duo of Bob Hope and Bing Crosby, whose "Road" movies were among that studio's biggest box office hits of the 1940s. The two Warner players never caught on like Bob and Bing, but their several films together all managed to turn a profit.
