Anubis

In 2008, Fox and Blue Sky acquired the film rights to the fantasy novel The Anubis Tapestry by Bruce Zick for an animated film titled Anubis. David H. Steinberg wrote the first draft for the film. The film was scheduled for release on March 23, 2018, but, by June 2017, it had been removed from its schedule for unknown reasons.

Why It Was Cancelled

 * The Disney / Fox Deal caused the cancellation.
 * There were 2 animated movies that came out March 23rd, 2018 titled Isle of Dogs and Sherlock Gnomes. So it probably would've avoided competition

Result

 * It is currently unknown if the film will ever get a release.
