Stephen Fry has replaced showbiz veteran Lord Attenborough as chairman of a charity trust set up to protect a historic theatre.
The comic said he could not "be more proud and pleased" to join the Criterion Theatre Trust which runs the venue in central London.
Chief executive Sally Greene said Fry's "extraordinary and limitless talents" would be an asset to the theatre.
The trust was set up in 1992 to oversee the refurbishment of the venue in Piccadilly, which first opened in 1874.
Fry said: "I couldn't be more proud and pleased to take over the chair vacated by the inimitable Lord Attenborough.
"Between them, he and Sally Greene have ensured that one of the absolute jewels of the West End is in a marvellous position to grow and flourish into the 21st century. I am insanely excited and honoured to take up this new position."
