Last weekend at the CTN Animation Expo, Lauren Faust revealed publicly that she was no longer working at Sony Pictures Animation on the feature film project Medusa.

Announced in summer 2014, Medusa was to have been the theatrical directorial debut of Faust, a 20-year industry veteran who gained widespread acclaim for her 2010 reboot of the My Little Pony franchise.

“I very much enjoyed my time at Sony Pictures Animation and was extremely excited about the progress our amazing team was making on Medusa,” Faust told Cartoon Brew today. “But, as it happens at so many studios with so many projects, we ultimately ran into creative differences on the direction of the project. I do not know if Medusa has been shelved, but I am no longer working on it or at Sony.”
