Thanks to ComicBook.com, several voice actors for the currently untitled 2020 theatrical film have been announced! It appears WB has taken the "celebrity voice" route for this film, casting Will Forte as Shaggy, Gina Rodriguez as Velma, and Tracy Morgan as Captain Caveman. Scooby-Doo will still be voiced by Frank Welker, though Fred and Daphne's voice actors have still not been announced at this time. ComicBook.com has also provided a plot summary, which appears to be very close to the same one we were given several years ago.
The animated reboot sees the Mystery Inc. gang join forces with other Hanna-Barbera characters to save the world from the scheming Dick Dastardly, the always-losing menace of Wacky Races who was accompanied by sidekick Muttley.
This negates the theory which some of us had of them pushing back the movie from its original 2018 release date to revamp the plot.
Additionally, Matthew Lillard and Grey DeLisle-Griffin, the typical voice actors for Shaggy and Daphne, have spoken out on Twitter, revealing that they were never told that they wouldn't be voicing their normal characters in the film, and in fact found out at the same time the general public did. Here's their comments on the matter:
Mindy Cohn, who was the previous voice of Velma before WB replaced her (without her consent in the matter) in Be Cool, Scooby-Doo!, also replied to Matthew Lillard's tweet.
