Renee Zellweger has returned to CAA after leaving for a 9-month stint at WME. I haven’t seen much of the Oscar-winner lately. When Sunday’s Academy Awards used past co-workers to give intimate introductions of Best Actor and Best Actress nominees, I wondered why Julianne Moore introduced Colin Firth (she noted she barely knew her A Single Man co-star) and not Zellweger, who made 2 installments of Bridges Jones’s Diary with Firth, with a 3rd in the works.
