Respected long-time talent representative Susan Smith, owner of The Susan Smith Co., died this morning at Cedars Sinai Medical Center surrounded by loved ones. She was 71. Smith, who had battled various cancers for decades, had been in the hospital since falling ill 18 days ago. On Wednesday, she underwent surgery for internal bleeding but by that time, she was gravely ill, so relatives and friends used the last couple of days to say their good-byes. “Susan is finally able to get a table in a booth next to her darlings Marion Dougherty and Phyllis Huffman in a place that was akin to her beloved “Carlyle Hotel,” Smith’s associate Charles E. Whitaker III said. Smith spent 44 years in the entertainment business, first as an agent and then as a manager, working with such long-time clients as Kathy Bates, Brian Dennehy, David Paymer and Melanie Lynskey, with whom she had a close bond.
