A highly anticipated chat between former CAA partners and longtime rivals Michael Ovitz and Ron Meyer scheduled for September 7 has now been postponed to September 29 due to Ovitz recovering from recent back surgery.

The duo will be meeting for a live discussion of James Andrew Miller’s Powerhouse: The Untold Story Of Hollywood’s Creative Artists Agency, an oral history of the agency Ovitz and Meyer co-founded in 1975 along with Mike Rosenfeld, William Haber, and Rowland Perkins. Ovitz and Meyer are the book’s main subjects, with their relationship detailed at length, and even if much is left out it’s become one of the industry’s most-talked about works of nonfiction. In particular because striking contrast is drawn between them, with Meyer emerging as the far more sympathetic player in the drama that saw the pair have one of Tinseltown’s most famous falling outs, both leaving the agency in 1995.

Originally set for the WGA theater, the Live Talks Los Angeles event was moved to the DGA and sold out quickly with tickets going for $25 and $65 apiece.

Variety first reported the news.
