Scooby-Doo 2: Monsters Unleashed reached cinemas in 2004. It is the direct sequel to the 2002 live-action Scooby-Doo film and again follows Fred, Daphne, Velma, Shaggy, and Scooby-Doo.
The sequel begins with Mystery Inc. investigating a museum event involving costumes and artifacts connected with old villains. The apparent monsters become real threats, creating a larger-scale adventure than the first film while retaining the series’ comedy and mystery structure.
Raja Gosnell directed both live-action theatrical Scooby-Doo films. The principal cast returned, including Freddie Prinze Jr., Sarah Michelle Gellar, Linda Cardellini, Matthew Lillard, and the computer-generated Scooby-Doo.
The year can be confused with the 2002 release of the first film or with later direct-to-video Scooby-Doo features. Monsters Unleashed was a theatrical sequel, not a television movie, and its release year is 2004.
