Satyrday

Satyrday 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 stolen from the sky by a nefarious owl and his army of ravens. A 14-year-old boy and his friend, an ages-old satyr, set up on the journey to restore the light to the night, and save the world from falling out of balance.

Why It Was Cancelled
The studio was facing financial problems following the video game crash of 1983, their second bankruptcy since the moderate performance of The Secret of NIMH.

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