Veteran actress Carol Lynley, known for her work across many decades in commercials, movies, and television, has passed away. As a performer, Lynley had been active since the mid '50s, acting and modeling for over five decades by the end of her career. Perhaps her most well-known role is that of The Poseidon Adventure, which saw her performing the Oscar-winning song "The Morning After." Reportedly, Lynley died on Tuesday at her Pacific Palisades, California home following a heart attack. She was 77 years old.

Born in 1942, Lynley's given name is Carole Ann Jones. For theatrical purposes, she used the stage name Carolyn Lee when she began child modeling in the 1950's. Upon her transition into acting, she learned the name Carolyn Lee had already been registered by another child actress, so Lynley simply combined the two names in a creative new way to come up with her new name. As Carol Lynley, the actress was soon impressing audiences both on Broadway and in Hollywood. By 1959, she was nominated for the Golden Globe Award for Most Promising Newcomer - Female following her performance as a pregnant teenager seeking abortion in the controversial drama movie Blue Denim.
