Snow White and the Seven Dwarfs is a 1937 American animated musical fantasy film produced by Walt Disney Productions and released by RKO Radio Pictures. Based on the German fairy tale by the Brothers Grimm, it is the first full-length cel animated feature film and the earliest in the Walt Disney Animated Classics series. The story was adapted by storyboard artists Dorothy Ann Blank, Richard Creedon, Merrill De Maris, Otto Englander, Earl Hurd, Dick Rickard, Ted Sears and Webb Smith. David Hand was the supervising director, while William Cottrell, Wilfred Jackson, Larry Morey, Perce Pearce, and Ben Sharpsteen directed the film's individual sequences.
Snow White premiered at the Carthay Circle Theater on December 21, 1937, followed by a nationwide release on February 4, 1938, and with international earnings of $8 million during its initial release briefly assumed the record of highest grossing sound film at the time.
In the late 30s and early 40s Walt Disney hired large teams of artists to work on films like Snow White and Bambi.
The cels which are used in the films them selves were drawn on celluloid, then hand-painted, photographed and placed on to film to be used in the making of the film. Once they had been used, the artwork was considered redundant and was often thrown away.
