Theatres and industry figures have expressed solidarity with the Black Lives Matter movement and urged others to use their voices to fight racism.
Those who have publicly backed the movement include London’s Bush Theatre, Hamilton writer Lin-Manuel Miranda, Sonia Friedman, Talawa Theatre Company, Ballet Black, the Royal Court and the Barn Theatre in Cirencester.
The announcements on social media follow widespread protests over the killing of George Floyd by a policeman in Minneapolis.
The Bush Theatre has suspended all normal activity on its channels for 24 hours in solidarity with Black Lives Matter, tweeting that it "does not feel appropriate" to release content that does not address recent events.
It will instead be sharing materials to help people educate themselves on the movement.
A statement posted by the theatre on Twitter said: "The last few days have been devastating. We’re all fighting a pandemic right now, but there is an ongoing pandemic that has been dominant for too long and that is racism.
"[...] Our building is closed so we can’t invite our family into our physical space in the way that we normally would, but we are here with you during this upsetting time.
"We will keep using our platform to represent black communities, to create opportunities with and for black artists, and to create work that reflects and challenges the world we live in, in the best way we can."
The statement adds: "Black Lives Matter. If you enjoy the black stories on our stages, and consume black culture then you need to use your voice too. We can all make a difference and there is more work to be done."
In a video posted on the Twitter account for Hamilton, Miranda said it was a "moral failure" that the official channels for the musical had "not yet spoken the inarguable truth that black lives matter and denounced systemic racism and white supremacy".
Miranda said: "I’m sorry for not pushing harder and faster for us to speak these self-evident truths under the Hamilton banner, which has come to mean so much to so many of you.
"Hamilton doesn’t exist without the black and brown artists who created and revolutionised and changed the world through the culture, music and language of hip hop.
"It doesn’t exist without the brilliant black and brown artists in our cast, crew and production team who breathe life into this story every time it’s performed."
He added: "While we live in a country where black people are under attack from emboldened white supremacy, police brutality and centuries of anti-black racism, its up to us in words and deeds to stand up for our fellow citizens, it’s up to us to be better allies and have each others backs."
A statement posted on Twitter by the musical Six said: "Six is a show that has been seen to champion diversity and empower black female-identifying voices, and we are so proud to have this position in the theatre community.
"We are also a show that is largely created and produced by white people – and like so many shows Six benefits from the talent and work of our black cast members and colleagues every day.
"It is therefore our duty to stand up for and support black people always – and not just when it’s trending – as to be silent is to be complicit."
A statement from Talawa Theatre Company said the organisation is "outraged and sickened by the murder of George Floyd at the hands of the state machine."
It added: "We stand in solidarity with our Black writers, artists, communities, friends and audiences here in the UK and elsewhere. We will ensure our platform is used for your voices to be amplified, your work to be shared and your communities represented."
In a statement on Twitter, Ballet Black said: “It’s positive to see dance companies responding to racial injustice.
"This is not just an American problem. It is worldwide. For us in the UK, it is demonstrated by the Windrush scandal. Stop and search. Hostile environment policy. Blackface in ballet as a *debate*. Online abuse for the creation of brown pointe shoes. And this is a shortlist."
The statement adds: "We’ve been here for 20 years trying to make a difference. Join the mission to lift black and brown voices up. Help change the power structure. Call out racism.
"Organisations, recognise that a 1000 daily micro aggressions tire the souls of your black and brown artists and staff. Gatekeepers, listen. Don’t tell us equality is sold, it’s not."
Other theatre organisations to announce solidarity with the movement include the Yard and the Almeida in London, HighTide theatre company, Manchester’s Royal Exchange and Northampton’s Royal and Derngate.
