This film was animated, I remember watching it in the very early 1990s but believe that it is older.
A girl lives in a palace in the clouds, she cannot remember anything because her captor uses makeup on her to erase her memory. I believe she is the princess of the kingdom. There are mice in the kingdom who are working to break the spell and help her remember who she is.
