  2. The WB-Discovery merger took place on April 8, 2022, resulting in many layoffs and shows leaving HBO Max.


  • It is unknown when the special will be released. The special was considered to be the second Hanna-Barbera Cinematic Universe film.
  • Cervone would say on the same day that the project was “practically finished”. Which means that the special's animation was fully finished few days before the cancellation. He even said he was practically scoring the film. Meaning that 90%-95% of the special's post-production was complete.
    • Later that month, it was reported that the film would still be finished, even though Warner Bros. Discovery had no current plans to release it.[1]
  • In November 4, 2022, according to Tony Cervone's Instagram. The cancelled film was finally "100%" finished.
