Christopher Cazenove is reportedly in a critical condition after collapsing at his home.
The actor, who is best known for playing Ben Carrington in '80s soap Dynasty, has been in intensive care for two weeks suffering from septicemia, reports The Mail On Sunday.
It is understood that the 66-year-old suffered migraines on a business trip to California and collapsed when he arrived home in London.
A friend said that the actor was in a coma but has regained consciousness and is being treated at the capital's St Thomas' Hospital. "He was in a life-threatening condition but doctors think they have stabilised him now. The family are all at his bedside and praying that he will make a full recovery," the source said.
Cazenove's agent said: "His family are with him and everyone is rallying round."
The Etonian made his name in the early 1970s drama series The Regiment, before making several appearances in Judge John Deed and playing the role of Charlie Tyrrell in The Duchess Of Duke Street.
