Caprice is a 1967 DeLuxe Color comedy-thriller film directed and co-written by Frank Tashlin starring Doris Day and Richard Harris.

All of this is actually a scheme devised by Sir Jason for Patricia to steal the formula for a new water-repellent hairspray, invented by Dr Stuart Clancy, May Fortune's head chemist.

Although finding Robert's killer is her main objective, Patricia is still devoted to Sir Jason, to whom she plans to give the hairspray.

Patricia goes to Switzerland and finds Madame Piasco – Clancy's mother-in-law – who is the actual expert who invented the formula.

Patricia tells Interpol that the narcotics were smuggled as May Fortune face powder, which was harmless until incinerated, when it turned into a hallucinogen.

Christopher shoots him dead from a distance, while Patricia flies the helicopter back to Paris and lands it atop the Eiffel Tower.

According to Fox records, the film needed to earn $7,200,000 in rentals to break even and made $4,580,000, meaning it lost money.

"[8] Roger Ebert was more amused, writing that "When everything has been said and done, you really have to stand back and admire the sheer professional competence of the people who make Doris Day movies ...

"[9] In her memoir, Day recounts an argument she had with her manager-husband Martin Melcher over the script for Caprice, unaware he had signed her name to the contracts before she had the chance to say no.

[10] On the DVD commentary, authors Pierre Patrick and John Cork discuss the ways the screenplay was rewritten, ostensibly to please the star.

They speculated that recent interest in Tashlin's signature mixture of slapstick, satire, and adventure—coupled with its Mod design—has acquired renewed respect from film buffs and, possibly, from Day herself.

The screenplay by Jay Jayson and Tashlin was novelized by Julia Withers and was published in paperback by Dell in February, 1967.
