Trivia, insights & behind the scenes
Frank Welker has voiced Fred since 1969 and Scooby since 2002—this film marks his 54th year in the franchise.
This crossover finally acknowledges what fans have demanded since the 1970s: Scooby-Doo exists in a universe where actual superheroes are real, making every previous 'guy in a mask' reveal slightly more absurd in retrospect.
