Aloha, Scooby-Doo is a 2005 direct-to-video animated comedy horror mystery film and the eighth in a series of direct-to-video animated films based upon the Scooby-Doo Saturday morning cartoons. It was released on February 8, 2005, and it was produced by Warner Bros. Animation, though it featured copyright and logo for Hanna-Barbera Cartoons at the end. It was also Ray Bumatai’s last performance before his death in October 2005. This movie, along with Scooby-Doo and the Cyber Chase, was the first Scooby-Doo movies to be re-released on Blu-ray on April 5, 2011. (Wikipedia)
As for films, 1991’s Showdown in Little Tokyo looks like a lot of fun indeed. I am looking forward to seeing that one.
