Oliviers: Company, The Inheritance and Come From Away among winners
A gender-swapping revival of the Stephen Sondheim musical Company was among the big winners at Sunday night's Olivier Awards.
It won four prizes at the ceremony - which is seen as the most prestigious awards event in UK theatre.
The West End revival of the 1970 musical saw the lead character, Robert, re-imagined as a woman, Bobbie.
The show's wins included the best supporting actress prize for theatre veteran Patti LuPone.
"I'm deeply moved, thank you for accepting me into your community," LuPone said as she accepted her trophy, adding: "I love London, I love the theatre community here."
Accepting the award for best musical revival, the show's director Marianne Elliott explained her company's "main goal was to put female stories front and centre on our stages".
"Celebrating female stories was not only possible but absolutely vital and the most outstanding thing about doing this show was that our audience seemed to believe that too."
Company also took home best set design and best supporting actor for Jonathan Bailey.
Two other shows took home four prizes from the ceremony - The Inheritance and Come From Away.
The Inheritance, which focuses on the lives of gay men in New York, was split into two parts when staged in the West End due to its seven-hour running time.
The show's prizes included best new play, best actor for Kyle Soller and best director for Stephen Daldry.
Come From Away's awards included best new musical, best theatre choreographer, best sound design and outstanding achievement in music.
The show tells the story of the Canadian town of Gander on 9/11, where 38 passenger aeroplanes were forced to land as the terror attack was taking place.
"When the world was in turmoil, this tiny town in Gander didn't question anything," John Brant told BBC News backstage.
"Their initial response was 'these people are in trouble and we need to help them, and I think that means a lot right now. I think audiences are being pulled towards a story which as about kindness, love and compassion."
Other Olivier winners included Sharon D Clarke, who said she felt "deep, deep joy" as she won best actress in a musical for Caroline or Change.
Best actor in a musical went to Kobna Holdbrook-Smith for his role as Ike Turner in Tina: The Musical.
Summer and Smoke took home two of the night's major prizes - best revival and best actress for Patsy Ferran.
The Duchess of Cornwall was among the attendees at the event, which took place at the Royal Albert Hall.
