A sequel series to classic Hanna-Barbera cartoon ‘The Flintstones’ is officially in development at Fox and is produced by Warner Bros. Animation; with Elizabeth Banks attached to star and executive produce. The new animated series titled ‘Bedrock’ is set 20 years after the events of the original series. Banks will voice an adult Pebbles Flintstone in addition to executive producing. In the show, Fred Flintstone is on the brink of retirement and 20-something Pebbles is embarking on her own career. As the Stone Age gives way to a shiny and enlightened new Bronze Age, the residents of Bedrock will find this evolution harder than a swing from Bamm-Bamm’s club.
