Disney's One Hundred & One Dalmatians was released in theaters on this day 61 years ago. This film (along w/ Sleeping Beauty) represents the apex of design in the studio's hand-drawn features. Here's a short thread about the key players responsible for the film's graphic mastery. Bill Peet wrote the film's adapted screenplay & boarded the entire film by himself, and during this process, he developed the initial look of the characters. He said it had taken 40 people on Pinocchio (which he also worked on) to do the same work he did alone on this film.
