Comedian Ricky Gervais is working on a series of TV documentaries focusing on his comedy heroes.

The Office creator has already lined up SEINFIELD creator Larry David and This Is Spinal Tap genius Christopher Guest to appear.

Gervais says, "Larry never gives interviews but he loves (Gervais' new UK show) EXTRAS. This is the upside to fame - meeting your heroes and finding out they're fans."
