# Hanna-Barbera Studios Europe

Hanna-Barbera Studios Europe Ltd. (also known as Great Marlborough Productions), formerly Cartoon Network Development Studio Europe and Cartoon Network Studios Europe, is a British animation studio headquartered in London, England, and owned by the UK division of Warner Bros. International Television Production, a subsidiary of the Warner Bros. Television Group, ultimately owned by Warner Bros. Discovery. It is the EMEA arm of Cartoon Network Studios.
On 7 April 2021, Warner Bros. Discovery predecessor WarnerMedia announced it had rebranded the studio to Hanna-Barbera Studios Europe, in honor of the original Hollywood-based studio and its founders William Hanna and Joseph Barbera. The Hanna-Barbera name had previously been revived on certain Warner Bros. Animation productions based on the classic franchises, including the fifth through thirteenth Scooby-Doo direct-to-video animated films, The Jetsons & WWE: Robo-WrestleMania! and the 2017 reboot of Wacky Races.
The first projects greenlit under the studio's new name were a film and sequel series based on The Amazing World of Gumball.
