As of October 2023, "Scooby-Doo 2: Monsters Unleashed" is available for streaming on platforms like HBO Max. However, availability can change, so it's a good idea to check your preferred streaming service or use a streaming aggregator to see where it's currently offered.

"Scooby-Doo 2: Monsters Unleashed" (2004) did not perform as well as expected at the box office, leading to a lack of enthusiasm for a third installment. The film received mixed reviews, and the franchise's direction shifted towards animated projects and direct-to-video releases instead. Despite some interest from fans, the combination of lower financial returns and changing market trends ultimately led to the decision not to produce "Scooby-Doo 3." Instead, the franchise has continued with various animated series and films.

"Scooby-Doo 2: Monsters Unleashed" was primarily filmed in Vancouver, British Columbia, Canada. The city provided various locations that stood in for the fictional environment of Coolsville, where the Mystery Inc. team solves mysteries. Additional filming took place at the Vancouver Film Studios, which facilitated many of the film's indoor scenes and special effects sequences. The use of Vancouver allowed the filmmakers to create a vibrant backdrop for the movie's mix of live-action and CGI elements.

As of now, there has been no official announcement regarding a new Scooby-Doo movie specifically set for release in 2025. The latest Scooby-Doo film is "Scooby-Doo: Holiday Haunt," which is set to premiere in late 2022. For updates on future Scooby-Doo films, it’s best to keep an eye on official announcements from Warner Bros. or other credible movie news sources.
