Prior to his work on The Guardians of the Galaxy, filmmaker James Gunn mostly served as a screenwriter for a variety of films, including the 2002 Scooby-Doo movie. Years ago he revealed that he had intended to make the live-action Scooby film "edgier," and that the first cut was rated R by the MPAA. At the same time he expressed his belief Velma was gay, and now he's outright said that the studio behind the film, Warner Bros., rejected the idea to depict her as gay in the film.
