Marianne Elliott has said the UK theatre industry is “on the crest of a wave” when it comes to diversity and female representation.

Her production of Steven Sondheim’s Company, at the Gielgud Theatre, leads the way alongside Canadian musical Come From Away in this year’s Olivier Awards, each receiving nine nominations.

Company, which features a female in the leading role instead of Sondheim’s original male casting, is nominated for best musical revival and best set design, with stars including Patti LuPone, Rosalie Craig, Jonathan Bailey and Richard Fleeshman also nominated.

Elliott has also received a nomination for best director alongside Stephen Daldry, Sam Mendes, Christopher Ashley and Rebecca Frecknall, who is nominated for Summer And Smoke.

She told the Press Association: “I think we are on the crest of a wave. I think the world is changing in the theatre industry and we’re starting to see a lot more diversity and a lot more females coming to the fore, and that’s really exciting in this country.”

She said her best director nod was a surprise, but it was “incredible to be amongst the other nominees because, you know, the men up there have always been the generation above me, leading lights if you like, and everybody knows them to be incredible, so it’s great to be up with them”.

“But it’s also, I have to say, brilliant to be up with Rebecca (Frecknall), I absolutely loved Summer And Smoke, so I’m just holding hands with her because I just feel so happy that we’re both up for the same category together, it’s brilliant.”

Elliott, who has also helmed sell-out productions of Angels In America and The Curious Incident Of The Dog In The Night-Time, is also a Tony award winner.

She said Company’s nine nominations were “completely unexpected”.

She said: “I mean it’s a total risk, what we did. We took a well-loved musical and put it straight into the West End with a female lead and changed every single theme because we swapped the genders round, so that’s a major risk.

“We thought it was worth taking, but we absolutely did not think that we’d come out with nine nominations.”

Asked about celebrating, she said she would probably be “drinking lots of champagne tonight with the company”.

She added: “This is the best bit! This is actually the best bit, because you don’t have to worry about competition, you just enjoy the fact that we’re all in it together, we’ve all been nominated and it’s theatre doing brilliantly.”

Elliott was awarded an OBE for services to theatre in the Queen’s Birthday Honours last year.

The Olivier awards will be held on April 7 at the Royal Albert Hall and will be hosted by comedian and TV presenter Jason Manford.
