After the success of Take Me Out to the Ball Game, Freed gave Donen and Kelly the chance to direct On the Town, released in 1949. The film was an adaptation of the Betty Comden and Adolph Green Broadway musical about sailors on leave in New York City and was the first musical to be filmed on location. Donen and Kelly had wanted to shoot the entire film in New York, but Freed would only allow them to spend one week away from the studio.  That week produced the film's famous opening number New York, New York. Away from both studio interference and sound stage constrictions, Donen and cinematographer Harold Rosson shot a scene on the streets of New York City that pioneered many cinematic techniques that would not be used again until they were popularized by the French New Wave ten years later. These techniques included spatial jump cuts, 360-degree pans, hidden cameras, abrupt changes of screen direction and non-professional actors. Donen's biographer Joseph A. Casper stated that the scene avoids being gratuitous or amateurish, while still "developing plot, describing the setting while conveying its galvanizing atmosphere and manic mood, introducing and delineating character." Casper also said that "Today the film is regarded as a turning point: the first bona fide musical that moved dance, as well as the musical genre, out of the theater and captured it with and for film rather than on film; the first to make the city an important character; and the first to abandon the chorus."  On the Town starred Kelly, Sinatra and Munshin as three sailors on a 24-hour shore leave in New York whose romantic pursuits lead them to Ann Miller, Betty Garrett and Vera-Ellen. The film was a success both financially and critically. It won the Academy Award for Best Music, Scoring of a Musical Picture and screenwriters Comden and Green won the Writers Guild of America Award for Best Written American Musical. Like Orson Welles, Donen made his directorial debut at 25. Donen stated that Kelly was "responsible for most of the dance movements. I was behind the camera in the dramatic and musical sequences." Kelly believed that he and Donen "were a good team. I thought we complemented each other very well."
