The Los Angeles Times reports that NBC has put a biographical mini-series into development on the life of famed Tonight Show host, Johnny Carson.

The mini-series will be based on Bill Zehme’s  Carson the Magnificent: An Intimate Portrait. The journalist spent time with Carson after his retirement.

The miniseries will look at the showman’s three-decade run (1962-92) on the Tonight Show. Carson is heralded as the greatest entertainer of all time and one of the busiest talk-show hosts in history, having logged 22,000 guest interviews in New York and Burbank.  While Carson was known for his privacy, the mini-series will attempt to offer a look at what his life outside the seminal set was like.

Zehme will serve as executive producer along with John Davies.
