This is a horrible, horrible rendition of The Hobbit, filmed only to be able to hang on to the movie rights for Tolkien's works. The story is butchered and the dragon's name is mis-stated. However, they do say my name correctly :)

Well considering it came out of a Soviet Bloc country in the mid-60s and it was directed by former-UPA/minimalist artist Gene Deitch...
Beautiful painting though and nice colour layouts. I can see the Little Golden Book influences.
