EXCLUSIVE: There are few relationships between a network and creator that have been as enduring as the one between David Milch and HBO. Now it has been extended with a new overall deal, which will keep Milch exclusive to HBO in television for two more years, bringing his tenure at the pay cable network to 14 years. Milch has been at HBO since 2002, when he embarked on developing his first project there, cult drama Deadwood, and under an overall deal since 2005. The relationship has yielded five pilots, three of which — Deadwood, John From Cincinnati and Luck — went to series. Milch’s most recent project at HBO was drama pilot The Money, about wealth and corruption among the super elite, which focused on an American mogul and patriarch (Brendan Gleeson) who wields power and influence to expand his media empire and control his family. HBO opted not to go forward with the pilot, co-starring Nathan Lane and featuring Ray Liotta and John Carroll Lynch, but the network remains very much in the David Milch business. He has other projects in the works, including a feature-length adaptation of a William Faulkner novel. Milch is repped by ICM Partners.
