Glory Anne Clibbery was born in Kenora, Ontario, Canada. She attended the Victoria Composite High School of Performing Arts in Edmonton, Alberta, Canada and at age 17 she emigrated to England to further her education at Webber Douglas Academy of Dramatic Art, graduating in 1976. She remained based in England but worked around the world as she pursued an acting career. She made her first movie, Cruel Passion, in 1974, at age 22. She worked on several films with the cult filmmaker Norman J. Warren including Prey and Outer Touch, and on the Australian production Felicity for John D. Lamond. Her other films include The Lonely Lady and bit-parts in Supergirl, Water and True Files. She was interviewed for the documentary about the Australian film industry. She did some radio and voice work including dubbing Anat Atzmon 'Nili' in the feature filmLemon Popsicle. She also appeared in several English television series in the 1970s and had leading roles in the theatre, including creating the role of Deborah Solomon in the David Mamet play, Sexual Perversity in Chicago in London's West End. She was featured on television in many commercials and began working as a commercial casting director in 1982. She was also a cartoonist, artist and writer.
In 2004, Clibbery, who was the former long term partner of racehorse owner Ivan Allan, was evicted, together with her mother Marguerite, from The Gables, a £1.7 million, nine-bedroom house in Newmarket, Suffolk owned by Allan after their 12-year relationship ended. Clibbery was a party to a landmark British court case, Clibbery v. Allan, which established that parties to ancillary relief court proceedings may generally expect the information they have provided about their finances to remain confidential and protected from publication. Since the deaths of Allan and Annen, the vast documents Clibbery compiled regarding her relationship with Allan have been released and are currently being edited for a series of books and exposés, of Allan, the British Court system and the alleged criminality within the horse racing industry.
