10 (styled as "10") is a 1979 romantic comedy film directed, produced and written by Blake Edwards, and starring Dudley Moore, Julie Andrews, Robert Webber, Dee Wallace, and Bo Derek, in her first major film appearance. Considered a trend-setting film at the time, and one of the year's biggest box office hits, the film made superstars of Moore and Derek. It follows a man who in middle age finds a young woman who he thinks is the ideal woman for him, leading to both a comic chase and an encounter in Mexico. The film would be the first of several sex comedies Blake Edwards would make: he addressed in this film subjects like sexual promiscuity, machismo, feminism, and aging. These themes went into Edwards' later comedies.
