Hans Bacher and Andreas Deja are artists and animators who have worked for Disney as well as other studios. Some time ago (2004 per one source) they were put to work doing character and design work for a proposed animated feature for Disney called Fraidy Cat.
As is usually the case, the project was shelved and will likely never come back. And as is sometimes the case, giving up on the project is a big loss. The film was "a charming crime story taking place in London of the sixties, a bit of HITCHCOCK’S ‘REAR WINDOW’ with animals," said Bacher. [caps and emphasis his]
Alas, Fraidy Cat will never be. But Deja and Bacher have posted some of their early concept art and oh boy, does it look like it would have been fun.
Deja worked on character design for Oscar and Corrina, a cat and a bird who were to be the film's protagonists. He also did a sizeable gallery of the various supporting cast:
Bacher worked on background and style designs that show off the script's proposed settings:
And is it just us, or does that cat look a little like Cary Grant?
