Overview
Scooby-Doo! and the Loch Ness Monster is a 2004 direct-to-video animated science fiction comedy film, and the seventh direct-to-video film based upon the Scooby-Doo Saturday morning cartoons. It was released on June 22, 2004, and it was produced by Warner Bros. Animation (although Warner Bros. had fully absorbed Hanna-Barbera Cartoons by this time, Hanna-Barbera was still credited as the copyright holder and the film ended with an H-B logo). Unlike the previous two films, it is no longer in the "classic format", and does not have the 1969 voice cast, and instead has Mystery Inc. voiced by their regular voice actors, and has them wear their outfits from What's New, Scooby Doo?. It is also the first film to have Mindy Cohn voice Velma, the What's New, Scooby Doo? theme song, and it has Grey DeLisle returning to voice Daphne since Scooby-Doo and the Cyber Chase.
Plot
The Mystery, Inc. gang travel to Loch Ness in Scotland to see the famous Blake Castle, the home of Daphne Blake's Scottish ancestors as well as her cousin, Shannon. The castle grounds are home to the upcoming annual Highland games, composed of many traditional Scottish sports. When they arrive, Shannon informs them that the castle has recently been terrorized by the Loch Ness Monster. Shannon says she has seen the monster and it is indeed real, a position shared by Del Chillman, a Loch Ness Monster enthusiast and amateur cryptozoologist, and Professor Fiona Pembrooke, a scientist who has put her whole career on proving the monster exists. Taking the opposite end of the argument are Colin and Angus Haggart, local competitors in the games, their father Lachlan and Sir Ian Locksley, the head judge of the games (as well as director of the Scottish natural history museum). Locksley and Pembrooke share a mutual hatred for each other (she was Ian's research assistant at his museum until he fired her for spending too much time on the Loch Ness Monster's trail).
That night, Scooby-Doo and Shaggy sneak out of their room to search for the kitchen and are chased by the monster, accidentally destroying the playing field in the process. Locksley sees the carnage and, enraged by Scooby and Shaggy's claims of almost becoming Loch Ness Monster victims, orders Shannon to repair the damage, threatening to demote the highland games to a miniature golf tournament if she doesn't. Velma discovers, to her surprise, that the Loch Ness Monster tracks head into town instead of the loch.
