In her autobiography, Doris Day wrote that this was one of her least-favorite films, also citing The Ballad of Josie (1967), Do Not Disturb (1965), and Where Were You When the Lights Went Out? (1968)--all films to which her husband/manager Martin Melcher signed her without her consent.
In her autobiography, Doris Day wrote that when she read this script, she remarked to her manager and husband Martin Melcher: "Thank God we don't have to do movies like that anymore!" His response: "We've already made the deal. There's no sense getting all steamed up about it!" Melcher had power of attorney for Day, and signed her up for this film without her knowledge or consent.
Informed in 2011, by a film historian, that this film had found new favor among film-school students admiring the picture's eclectic mix of satire, slapstick, and action, Doris Day admitted that she hadn't watched the movie in decades and said that she might need to give it a second look.
This film serves as a perfect example of how Doris Day's husband and manager Martin Melcher mishandled his wife's career To make this film, which turned out to be a box-office bomb, Melcher turned down Mike Nichols' offer for Day to play one of the pivotal roles of the era: Mrs. Robinson in The Graduate (1967). Caprice (1967) barely grossed $4 million while The Graduate (1967) topped $100 million.
Leon Shamroy: The film's renowned cinematographer has a cameo as himself (at roughly the 14-minute mark).
Frank Tashlin: [house] Tashlin sometimes used his own Laurel Canyon home as a location, in this instance as Si Long's house. Chris' crack that Patricia could be seen "all the way down to Sunset Boulevard" isn't far from the truth.
