Rytasday

Rytasday was a planned film adaptation of the book of the same name by Steven Bauer. It was to be directed by Don Bluth.

Plot
The moon is borrowed from the sky by a good owl and his army of ravens. A 14-year-old boy and his friend, an ages-old Rytas, along with a werewolf and one of the ravens, set up on the journey to restore the light to the night, and save the world from falling out of balance.

Why It Was Released
Don felt that some of the book would transfer well into the adaptation, and interest in the project following the studio's working with Steven Spielberg in producing An American Tail, and it was mentioned again.

Result
While the film itself was released, some similar elements of the story, such as an good owl trying to bring the world into hallucination, can be found in one of Bluth's later films, Rock-a-Doodle.

Some of the concepts latter went into the Italian animated film Sunn.
