The British star, best known for his role as Ben Carrington in the glamorous 1980s soap opera, passed away in a London hospital on Wednesday (07Apr10).
Cazenove was taken ill at the end of February (10) and admitted to St Thomas' Hospital in the British capital, where doctors diagnosed him with septicaemia. He spent over a month in an intensive care unit fighting for his life before his death this week (07Apr10).
Cazenove's passing comes just days after the death of his onscreen brother John Forsythe, who played Blake Carrington in the show.
Forsythe died last Thursday (01Apr10) at the age of 92.
A statement from Cazenove's agent Lesley Duff confirms the sad news: "Christopher died peacefully on April 7 surrounded by his loved ones having contracted septicaemia at the end of February. Despite a valiant fight and the untiring efforts of the wonderful team at St Thomas', he was overwhelmed. All who knew and loved him will be devastated by the loss of this incredible man who touched so many lives."
Cazenove's first major role came in 1970s U.K. TV show The Regiment, and he went on to star in a string of films before landing the part that made his name, playing opposite Joan Collins in Dynasty between 1986 and 1987.
The actor went on to star in notable movies including 1990's Three Men and a Little Lady, the sequel to Three Men and a Baby, and 2001's A Knight's Tale, in which he played the father of Heath Ledger's character.
He was last seen in British TV series Hotel Babylon in 2009.
Cazenove is survived by his son Rhys, from his marriage to actress Angharad Rees. The former couple's eldest son, Linford, was killed in a car crash in 1999. Cazenove was in a relationship with girlfriend Isabel Davis, who he had been dating since 2003, at the time of his death.
