Hines died Friday at her home in Beverly Hills from complications of heart problems, said Alan Young, her 'Mr. Ed' co-star. 'I lost a great friend. She was always joyous,' Young said Monday. In the show, which ran from 1961-1966 on CBS, the Posts moved into a rambling country home only to find a horse in their barn. The center of the show became the banter between Young and Mr. Ed, which left Hines trying to make the most of her opportunities. The part was 'a tough chore,' Young said. 'She was a girl married to a fellow listening to a horse. Her biggest line was `lunch is ready.' The rest of it was reacting to it. Connie never complained. How many actors would react that way?' 'Mr. Ed' built a new generation of fans with reruns airing on syndication and cable. 'You know we have a whole new audience,' Hines said on 'CBS This Morning' in 1991. 'I still get letters and now they're from 4-year-olds and 5-year-olds and it's just wonderful. People stop me on the street and they say, you know, `Thank you for being my baby sitter.' ' Hines was born June 5, 1930, in Dedham, Mass. In Young's 2007 book 'Mr. Ed and Me and More,' Hines wrote a section about her career, describing her childhood in a show business family. 'I was bitten by the bug when I played the part of Mary to my father's Clarence Day in `Life With Father' on stage in Boston,' Hines wrote. After her first marriage ended in divorce, she moved to New York. Hines got some work modeling and appearing in commercials, then landed a romantic leading role in a CBS anthology series 'Rendezvous' that was shot in Europe. 'When I came back to New York, CBS told me I should go to Hollywood and would do well there,' Hines wrote. 'So in 1959 with $200 in my pocket, and armed with two letters of introduction ... I flew to Hollywood.' She won a role in the 1960 film 'Thunder in Carolina', which Hines called 'a forgettable feature ... about stock car racing,' and some episodic television appearances in shows such as 'Johnny Ringo' and 'The Millionaire' in 1959 and 'Sea Hunt' and 'Riverboat' in 1960, then she got her big break with 'Mr. Ed.' She didn't have a phone yet in her apartment, so when her agent said the producers were going to call, she waited for the news at a gas station. 'I waited three hours for that call having coffee after coffee after coffee,' she told the Los Angeles Times in 1996. After 'Mr. Ed' finished, Hines worked on television sporadically in such shows as 'Medical Center,' 'Mod Squad' and 'Bonanza.' In 1970, she married Lee Savin, an entertainment lawyer and producer. Hines hosted a local cable access show about animals, interviewing veterinarians and animal behaviorists and offering animals for adoption. Young and Hines performed together in 1996 in Irvine in 'Love Letters,' which deals with the correspondence of a man and woman over 50 years. Savin died in 1995.
