According to Walmart.com, the next LEGO Scooby-Doo movie, Blowout Beach Bash, will be released on Tuesday, July 25. In addition, Amazon lists that the digital release date will once again be two weeks prior, on July 11. You can already pre-order the movie at both the links provided above. Nothing else about the DVD is known at the moment, though I imagine we will soon be finding out what the special features and/or bonus episodes will be.
Though this is unrelated, since this is such a short post and it doesn't really warrant it's own post, according to Variety Insight, S.C.O.O.B. is now simply being referred to as "Untitled Animated Scooby-Doo Film," meaning that S.C.O.O.B. will no longer be the title for this film. It's also probably safe to presume the reason for the release date delay is due to the film either being partially or completely retooled.
Fans already frustrated with how WB has been treating Be Cool Scooby-Doo will be very disappointed with what they announced today.
Today, Variety reported that representatives from WB have announced that the upcoming theatrical film S.C.O.O.B. will not be released on September 21, 2018, and has been pushed back nearly a full two years, to May 15, 2020. No reason was provided by WB for the excessive delay in release date. It is also worth noting that WB did announce two more film release date delays ("Tag," "Godzilla vs. Kong" in addition to S.C.O.O.B., though both films were only delayed a single week.
It honestly makes me wonder if something is going on behind-the-scenes at WB causing all these delays, both from Be Cool Scooby-Doo and now S.C.O.O.B.. It seems very peculiar that the other delayed films were only delayed a single week, while S.C.O.O.B. was delayed an excessive two years.
According to Variety, Dax Shepard will now be the co-director of S.C.O.O.B., along with Tony Cervone, one of the head writers for Scooby-Doo! Mystery Incorporated. In addition to Shepard and Cervone, Matt Lieberman and Dan Povenmire (who is most famous for his work on the hit TV series "Family Guy") will be producing the film, while Jesse Ahrman will be overseeing the film's production and directing.
From Movie Insider, here's the official summary from Warner Brothers for the upcoming animated Scooby-Doo movie "S.C.O.O.B.":
Since the beginning of time, an epic battle has waged between humans and ghostly forces of evil, and only the spell of a powerful canine warrior can keep the spirits at bay. When the spell begins to weaken, S.C.O.O.B. – an elite group of heroes comprised of the most beloved Hanna-Barbera characters – recruit Scooby-Doo to find the enchanted collar that is the key to stopping the impending ghost attack. Together with his new group of allies and the original Mystery Inc. gang, Scooby-Doo embarks on the ultimate adventure to save man (and dog) kind!
This Tuesday at CinemaCon 2016, the previously untitled Scooby reboot's (which will be released on September 21, 2018) name was revealed to be "S.C.O.O.B.". In addition, "S.C.O.O.B." will be the "our first shot at unlocking the Hanna-Barbera universe" according to director Tony Cervone, meaning that there will be other interconnected Hanna-Barbera reboot movies released in the coming years. Some concept art was also revealed at CinemaCon 2016, which can be seen above (credit goes to SpiderScooby over at ScoobyFan.net for finding the concept art)
