Father-in-law of actress Billie Piper who is married to his son Laurence Fox.
Fox left the acting profession for nine years (1970-79) after he filmed Performance (1970) with Mick Jagger. A combination of his father's recent death, the strain of filming and smoking the hallucinogen DMT with Mick Jagger led to a nervous breakdown. Fox subsequently joined a religious organisation known as "The Navigators" which is similar to the Gideons and is closely associated with the ministry of Billy Graham.
Had a relationship with the actress Sarah Miles in the early 1960s.
He played King George V in W.E. (2011), in which his son played Laurence Fox played King George VI. His elder brother Edward Fox had previously played George V's son and eventual successor King Edward VIII (the Duke of Windsor) in "Edward & Mrs. Simpson" (1978).
He replaced actor John Woods in the Old Vic's early 2006 production of the Arthur Miller play "Resurrection Blues", which was directed by Robert Altman in his London theatrical debut, one month before previews began. The play was widely panned by critics, partly due to the divergent acting styles of the eclectic cast assembled by Robert Altman, which included the Swiss actor Maximilian Schell as Fox's character's cousin.
His Patriot Games (1992) cast mate, Richard Harris, was also his niece's former father-in-law.
Middle brother of Edward Fox and Robert Fox.
The second of three sons of Angela Fox and the theatrical agent Robin Fox.
Uncle of actress Emilia Fox and Freddie Fox.
