Behind the Scenes Featurette from the movie Lady and the Tramp (1955).

Lady and the Tramp is a 1955 American animated musical romance film produced by Walt Disney and released by Buena Vista Film Distribution. It was directed by Clyde Geronimi, Wilfred Jackson, and Hamilton Luske, and features the voices of Barbara Luddy, Larry Roberts, Bill Thompson, Bill Baucom, Verna Felton, and Peggy Lee. The film was based on the 1945 Cosmopolitan magazine story "Happy Dan, the Cynical Dog" by Ward Greene, and tells the story of Lady the pampered Cocker Spaniel as she grows from puppy to adult, deals with changes in her family, and meets and falls in love with Tramp the homeless mutt.

Lady and the Tramp was released to theatres on June 22, 1955, to box office success. It was the first animated film to be filmed in the CinemaScope widescreen film process, as well as Disney's first animated film to be distributed by their Buena Vista division following their split from RKO Radio Pictures. It initially received generally mixed reviews from film critics, but critical reception for the film has been generally positive in modern times. A direct-to-video sequel, Lady and the Tramp II: Scamp's Adventure was released on February 27, 2001, and a live-action/CGI hybrid remake premiered on November 12, 2019, as a launch title for the Disney+ streaming service.

In 2023, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically or aesthetically significant."
