Fans want him to launch another standup tour or host his own show again, but Rock has been busy mentoring some fresh faces instead. He helped sell and executive produces comedian W. Kamau Bell’s first TV show, “Totally Biased,” which just got picked up for a second season on FX, and is now producing YouTube star Deshawn Raw’s sketch comedy pilot “D-Raw” for Comedy Central. Rock is also finishing a documentary about New York comedy club Comic Strip Live. (And who else got a career boost from working with Rock? An unknown young comic named Louis C.K.)
