EXCLUSIVE: Rand Holston is leaving CAA, the talent agency where he spent the last 28 years. I’m hearing this might be one of several exits to take place over the next three weeks. The agency confirmed that Holston is leaving. I’m told he is meeting with other agencies, and he will land at one of them before year’s end. His longtime writer and director clients include Stephen King, Rob Reiner, Wolfgang Petersen, Robert Towne, John Moore, Marshall Herskovitz, Jordan Kerner, Ed Zwick, Jim Ivory, Bruce Robinson and Jon Avnet.
