FOX is looking to return to Bedrock. The network is working with Warner Bros. Animation on an adult spin-off of the venerable primetime animated series The Flintstones.

Bedrock catches up with the Flintstone family two decades after the original, with Fred on the brink of retirement and 20-something Pebbles (to be voiced by Elizabeth Banks) 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.

If picked up to series, Bedrock will be co-produced by Warner Bros. Animation and FOX Entertainment. Elizabeth Banks and Max Handelman will executive-produce through Brownstone Productions.
