Diane Keaton's Book Club costar Ed Begley Jr. exclusively opened up to Us Weekly about her shocking death at age 79. "I need to control my emotions," a choked-up Begley, 76, told Us at the Environmental Media Association (EMA) Awards on Saturday, October 11. "I was extremely close to Diane. I loved her a lot." The pair first starred together in the 1992 TV movie Running Mates, and more recently appeared in the hit 2018 romantic comedy Book Club, which made more than $100 million at the box office.
