Personal life Family Schell's brother, Paul Rudolf (born 1940), now known as Paul von Schell, has acted in German-language productions. A younger brother, Peter (1941–68), died young. Through a German great-grandfather, Schell is related to Louis XIV of France (1638–1715), Philip II, Duke of Orléans (1674–1723), Regent of France and Francis I, Holy Roman Emperor (1708–65). She is not believed to be related to the Austrian-Swiss actors Maximilian and Maria Schell. Marriages While filming Amsterdam Affair in 1968, Schell met and married her first husband, British actor William Marlowe (1930–2003), and moved to London. The marriage ended in divorce in 1977. Schell married director Bill Hays (1938–2006) in 1982. In 1984, they worked together for the first time as husband and wife on a TV production of Ivan Turgenev's play A Month in the Country. Retirement Schell's career continued into the mid-1990s, after which she retired from acting and opened Chambre d'Hôtes Valentin, a small guesthouse in Bonneval, Haute-Loire, France, which would become a popular destination for fans of Space: 1999. She reportedly sold the inn after the death of her second husband in 2006. Schell made her first convention appearance at MainMission:2000, a celebration of the 25th anniversary of Space: 1999 held in New York City. To date, she has appeared at only one other convention, mainly due to her second husband's declining health. Schell contributed a foreword to the Space: 1999 novel Born for Adversity, written by David McIntee and published by Powys Media in 2010. Schell's autobiography A Constant Alien was published in 2016. She
