Notting Hill and Gladiator actor John Shrapnel has died at the age of 77, the National Theatre says.
The arts venue led tributes to the star, describing him as a "wonderful actor".
"We're very sad to hear that the wonderful actor John Shrapnel has died. He performed in many productions at the National Theatre, including Phedre - our first @NTLive production," it said.
Shrapnel had reportedly been suffering from cancer.
He was a respected theatre actor but had also appeared in a number of films, including 101 Dalmatians, The Duchess and Alien Autopsy.
Richard E Grant was among those sharing their condolences, writing on Twitter: "Sad to learn that John Shrapnel has died. I played his patient in HOW TO GET AHEAD IN ADVERTISING (1989).
"Generous, kind, funny and warm hearted. Privileged to have known and worked with him."
Actress Maxine Peake shared a photo with Shrapnel, who had starred alongside her in Hamlet, saying: "We have lost another great. The incomparable John Shrapnel.
"Honoured to have worked with him. Privileged to have called him a friend."
Stage actor Hadley Fraser said he had "loved" Shrapnel and "learned a great deal from him".
Director Duncan Jones described the late actor as a "delightful, generous person", adding: "John was one of a handful of actors, far too talented for my early career, to agree to work with me just after I left film school.
"I made a short film called Whistle, and he agreed to spend a day working on it, elevating my short into something I was later able to enter in festivals & leverage into real, paid work."
Shrapnel was a member of the Royal Shakespeare Company and also had experience as a voiceover actor.
He is survived by his wife Francesca and three children.
