Cooper got along well with most of Griffith's company including Dorothy Gish, Mary Alden, and Mae Marsh. She also was friends with Norma Talmadge, Mabel Normand, and Pola Negri. Though they were not close, she was fond of Lillian Gish. Cooper didn't get along with Teddy Sampson and she greatly disliked Theda Bara, who she felt was trying to steal Raoul Walsh away from her during the making of "Carmen" and "The Serpent". In later years Cooper was good friends with Carole Lombard, whom she helped get some of her first roles. Cooper and Walsh were good friends with Charlie Chaplin in 1924. Chaplin was going through some troubling times and she found him gloomy and needy. She enjoyed him more once his personal life was back in order and he was much more cheery.
