Seth MacFarlane's ‘Flintstones’ Reboot Put on Indefinite Hold

Schedule conflicts on part of “Family Guy” boss Seth MacFarlane put plans for “Flintstones” revival on ice

Sorry, Seth MacFarlane fans: when it comes to his planned "Flintstones" reboot, the operative phrase is now, "Yabba Dabba Don't."

The revamp of the classic cartoon about a prehistoric working schlub and his family, which was to air on Fox, has been put on ice indefinitely, due to schedule concerns on MacFarlane's part.

Fox announced the series last May, with a plan to premiere the new "Flintstones" in 2013.

Though the news may disappoint, it's hardly surprising that MacFarlane should find his plate too full. He already has three series — "Family Guy," "American Dad" and "The Cleveland Show" — running on the network, for which he provides multiple voices.

Deadline first reported the news.
