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 based in London and owned by the UK division of Warner Bros. International Television Production, a subsidiary of the Warner Bros. Television Group, the television business segment of Warner Bros. Discovery. It is the EMEA arm of Cartoon Network Studios.

On 7 April 2021, WarnerMedia, a predecessor to the current-day Warner Bros Discovery, announced that the studio had rebranded as Hanna-Barbera Studios Europe, paying tribute to the original American studio, founded by Oscar and Emmy winners William Hanna and Joseph Barbera on 7 July 1957. The Hanna-Barbera name had previously been revived on some Warner Bros. Animation series and films based on the classic franchises, including from the fifth to thirteenth Scooby-Doo direct-to-video animated films, The Jetsons & WWE: Robo-WrestleMania!, the 2017 reboot of Wacky Races and Yabba Dabba Dinosaurs.

The first projects to be greenlit under the new name were a new series and a film relating to The Amazing World of Gumball.
