Scoob! Holiday Haunt

Scoob! Holiday Haunt is an unreleased American animated mystery comedy film based on Hanna-Barbera's Scooby-Doo franchise, produced by Warner Bros. Pictures and Warner Animation Group. It was set to be a prequel of Scoob! (2020). The film follows a young Mystery Incorporated investigating a mystery in a holiday-themed resort.

The film was directed by Michael Kurinsky and Bill Haller from a screenplay by Paul Dini and Tony Cervone, and stars Frank Welker, Iain Armitage, Ariana Greenblatt, Mckenna Grace, Pierce Gagnon, Mark Hamill, Michael McKean, Andre Braugher, Cristo Fernández, Ming-Na Wen and Maya Hawke.

The film was to be released on HBO Max in December 2022. Warner Bros. Discovery shelved the film that August, citing cost-cutting measures and an intent to refocus on theatrical films over projects made for streaming.

When the park is beset by a ghostly haunting, the kids must solve a 40-year-old mystery to save the resort and show Scooby the true meaning of Christmas.^[2]
