Please file this item under the "Duh" file: Dr. Mehmet Oz, Oprah's favorite medical expert, is getting a spin-off talk show. Harpo Productions, Oprah's company, is developing a Dr. Oz talk show to commence fall of 2009.

According to insiders, the Harpo team had meetings with distributor in Chicago last month. A medical talker with Doc Oz, which I bet will be called Ask Dr. Oz -- the name of his successful segments on Oprah's show -- would follow in the footsteps of Dr. Phil. Remember, Dr. Phil McGraw began his life as a talker by appearing on Oprah in infrequent hours that were a de facto pilot for his own talk show. Dr. Phil then launched in 2002, as a Harpo production, and has been a big time hit. He's even challenged Oprah in some markets.
