Casper is Coming Back...with Sabrina?!

I'm developing a Feature Film called "Casper's Screams Academy" with Characters from "Sabrina, the Animated Series" It's about Casper going to Screams Academy, But will he and sabrina fit in. With returning characters like Spooky the Tuff Little Ghost (Casper's Cousin), Poil, Spooky's Ghoul-Friend, The Ghost Trios, The Harveys, Salem, etc. With new characters like Mr. Green, The vampire who retired from biting people's necks and Tuffy, Spooky Little Sister wanna cause trouble by Beating up People.

The Project is in Pre-Production, Hoping to I get Permission with Harvey Comics & Archies Comics.
