Yesterday, Variety announced that Chris Colombus was officially named creative producer of the upcoming Scooby-Doo theatrical movie (formerly known as S.C.O.O.B.) currently slated for a May 15, 2020 release date. Colombus became interesting in producing the film while he was in the process of creating Gremlins. Tony Cervone is still directing the film. However, the article made no mention of Dax Shepard (who was previously announced to be Cervone's co-director), so it is possible that he is no longer working on the project. WB Animation has disclosed that Colombus has a great affection for Scooby-Doo, and cares very much about the future of the franchise. Kelly Fremon Craig is writing the screenplay, amended from Derek Elliott and Jack Donaldson's original draft. Matt Lieberman wrote the original draft, which has since been discarded and completely rewritten. Though the article did not explicitly state this, it is very likely that this is the reason from the movie's postponement from the original September 21, 2018 date.
Colombus is most famous for his work on the Harry Potter, Home Alone and Percy Jackson films.
