Jack Lemmon wrote that he thought this was a good, funny movie that didn't do well because of its "terrible title". He thought he and Doris Day had very good chemistry together, and he regretted that they never did another film.
Doris Day wrote that her manager/husband Martin Melcher was terribly concerned over the box-office failure of this film and The Tunnel of Love (1958). Their failures caused Day to drop out of the Top Ten Box Office Stars. Day and Melcher had words about him hustling her into almost any film for the money instead of waiting to find good scripts that would have produced better results.

This was one of Doris Day's rare total failures at the box office, so much so that Columbia tried re-releasing it under the title Twinkle and Shine. The second release was no more successful than the first. Later that year, Day enjoyed one of the biggest hits of her career, "Pillow Talk" (her first film co-starring Rock Hudson), and by the end of 1959, Day placed 4th on the Top Ten Box Office Stars list.
This film's director, Richard Quine, had a reputation for making perfectly charming films that somehow never caught on with moviegoers. His other credits include Audrey Hepburn and William Holden in Paris When It Sizzles (1964), and the Jack Lemmon with Janet Leigh version of My Sister Eileen (1955).
