Scoob!/Trivia


 * Executive Meddling: Tony Cervone, the film's director, has stated that this was behind the recasting of the characters' voice actors - he wanted to use the characters' original VAs, but Warner Bros. thought it would be better to use an All-Star Cast instead.
 * Missing Trailer Scene: The scene from the first trailer where Puppy!Scooby licks Shaggy, and Shaggy licks him back, leading to Scooby saying "Don't do that again," never happens in the film proper.
 * The Other Darrin: With the exception of Frank Welker as Scooby, all of the Mystery Inc. members were recast for this film:
 * Will Forte plays Shaggy instead of Matthew Lillard.
 * Instead of being voiced by Grey DeLisle, Daphne is voiced by Amanda Seyfried.
 * Velma is played by Gina Rodriguez rather than Kate Micucci, who has been the voice of Velma since 2016.
 * Zac Efron and Ken Jeong respectively replace Welker as the voices of Fred Jones and Dynomutt.
 * What Could Have Been: When the idea for this film was originally conceived, it was going to be a hybrid live action/CGI film like the first two theatrical movies and the two Made for TV Movies, before it was decided that this movie would be entirely in CGI.
