Lord Richard Attenborough is in a stable condition after suffering a fall at his home, a hospital spokesman has said.
The 85-year-old actor and director was forced to pull out of a plaque-unveiling ceremony after the accident.
A spokesman for St George’s Hospital in Tooting, south-west London, said: “Richard Attenborough suffered a fall at his home and is receiving care at St George’s Hospital. He is currently in a stable condition.”
Lord “Dickie” Attenborough had been due to honour Brief Encounter star Dame Celia Johnson on Thursday, the centenary of her birth. A spokeswoman for the event said: “He had a fall and he wasn’t able to do it.”
She said the accident happened earlier this week.
The English Heritage blue plaque was placed at 46 Richmond Hill in Richmond upon Thames, Surrey, where she was born and lived until 1924.
Born in Cambridge in 1923, Lord Attenborough has championed the British film business through its triumphs and trials for more than 60 years as actor, Oscar-winning director and prolific movie-maker.
Gandhi is the highlight of his career, clinching eight Oscars, including best film and best director.
Lord Attenborough lives in Richmond upon Thames. He married actress Sheila Sim when he was 21. He is the older brother of Sir David Attenborough.
