10 is a 1979 American romantic comedy film written, produced and directed by Blake Edwards and starring Dudley Moore, Julie Andrews, Robert Webber, and Bo Derek.

The film follows a middle-aged man who becomes infatuated with a young woman whom he has never met, leading to a comic chase and an encounter in Mexico.

George visits the minister who performed the wedding and learns that the woman is Jenny Miles, daughter of a prominent Beverly Hills dentist.

The following day, while spying on his neighbor, George hits himself with the telescope and falls down an embankment, causing him to miss Sam's phone call.

Sam finally reaches him on the phone, but mistakes him for an intruder and calls the police, who hold George at gunpoint while trying to understand his gibberish.

George visits his neighbor's house to take part in an ongoing orgy, but Sam spots him through his telescope, widening the rift between them.

10 originally had a budget of $5-6 million and was due to start filming on October 2, 1978 but George Segal didn't show up and the production was cancelled.

The site's consensus states: "Blake Edwards' bawdy comedy may not score a perfect 10, but Dudley Moore's self-deprecating performance makes this midlife crisis persistently funny.

[9] Vincent Canby of The New York Times described 10 as "frequently hilarious", praising the performances by Moore and Andrews and concluding that the film "is loaded with odd surprises".

[15][16] The film also brought renewed fame to the one-movement orchestral piece Boléro by Maurice Ravel, whose music was still under copyright at the time.

As a result of the film, sales of Boléro generated an estimated $1 million in royalties and briefly made Ravel the best-selling classical composer 40 years after his death.
