Poor Cinderella is a 1934 Fleischer Studio animated short film featuring Betty Boop. The first entry in the Color Classics series, Poor Cinderella was Fleischer Studio’s first color film, and the only appearance of Betty Boop in color during the Fleischer era.
The short was made in the two-strip Cinecolor process, because Walt Disney had exclusive rights to the new 3-strip Technicolor process from 1932 to 1935. (The remaining Color Classics from 1934 and 1935 were made in two-color Technicolor.) Betty’s hair was colored red to take advantage of this. The short also used Fleischer Studio’s Rotograph process, in order to provide some scenes with additional depth of field. Along with many of the other Color Classics, Poor Cinderella is today in the public domain and can be freely downloaded from the Internet Archive, among other locations.
Rudy Vallee appears in caricature, singing the title song during the ball sequence.
