The most significant shift in came in 2002 with the live-action Scooby-Doo film directed by Raja Gosnell. Written by James Gunn (yes, the Guardians of the Galaxy director), the film was marketed to kids but packed with adult-oriented parody. Gunn famously wanted to make a satire of the original series, leaning into Shaggy’s implied drug use (though censored), Velma’s skepticism, and the group’s dysfunctional psychology.
