James Gunn, famous for his superhero films like “Guardians of the Galaxy” and “The Suicide Squad,” began his career as a writer by contributing to the blockbuster movie franchise “Scooby-Doo!” Gunn wrote the first film, “Scooby-Doo!”
Warner Bros. launched two films in 2002 and 2004, showcasing the Mystery Inc. group, fronted by Freddie Prinze Jr., Sarah Michelle Gellar, Matthew Lillard, and Linda Cardellini. The box office collection for both movies amounts to a total of $456.9 million. The fans of the franchise are anticipating the reunion of the original cast for a potential third movie.
It appears that Gunn is confident about the possibility of making a “Scooby-Doo 3!” if the original cast is on board. This sentiment was expressed after journalist Brian Particelli shared an interview in which Matthew Lillard (who played Shaggy) expressed his interest in reprising his role for a potential third film.

After the conversation gained traction, Gunn took notice and left a positive comment but also noted that he is currently occupied with other projects and cannot give serious consideration to the idea at the moment.
