Three Blind Mice (1945)

George Dunning, like his contemporaries John Hubley and Norman McLaren, can best be described as an experimentalist, having used every medium to make animated films, including cut-outs, painting on glass, and direct painting onto film as well as more orthodox methods such as cel and paper. But he hahs been marked him as an individual talent for is use of articulated, painted, metal cut-outs.
The first films from the NFB animation unit were cut-outs, because of the equipment limitations they faced (all they had was a 35mm title stand with a vertically mounted camera). The first cut-outs were jointed or unjointed and made out of cardboard and soft metal sheets.

Dunning simplified the process and the method of making the joints. He used black thread between the shoulders and the bodies to provide greater flexibility.He needed two assistants, the animators Grant Munro and Robert Verrall, to complete this film.
Three Blind Mice tells of horrific factory accidents that befell three mice that work there. It's an educative and bizarre film because this short, using simple cut-out animation and the song "Three--- Blind--- Mice----", illustrates why industrial safety rules must be observed.
The nursery rhyme favorites prove no less foolish in the factory than when they provoked reprisal from the farmer's wife. They disobey all the safety rules with dire results.
