Idris Elba's open audition for extras in Hoxton was "shut down" after police were called following concerns over the amount of people outside the venue.
The Guerilla star had announced he was looking for paid extras for his upcoming film set in Hackney's Afro-Carribean community on his Instagram page, which was to take place at Whitmore Community Centre in Hoxton between 4pm and 9pm.
Two hours into the audition yesterday evening, it's claimed a member of staff phoned the police due to the huge crowds causing health and safety concerns.
A Metropolitan Police spokesperson said (via Hackney Citizen): "Officers attended the location and spoke with staff. The planned event - an audition - has been cancelled by the organisers following discussion with police."
During the audition, Elba - who will be directing the east London-based production set in 1983 - posted a clip on his Instagram page to let fans know that the event was likely to be "shut down" due to the high turn out of auditionees.
"The response for the open casting has been unbelievable - thank you so much for sharing the info and for coming down if you've come down," the Beasts of No Nation actor said in his Instagram clip.
"If you're standing in line, I promise we'll try and see everyone but already I'm asked to shut it down because of the numbers. I don't want to shut it down, but it's looking very likely- I'm just being honest with you guys.
"The alternative is to send a headshot of yourself with a bit of information to Key Casting, and we will look at it for my film and others. Thank you so much for coming down and supporting me."
One fan described it as "pure chaos" but a "great buzz", while others commended Elba for giving fans the opportunity to audition.
The 44-year-old star grew up in Hackney after his mother moved to the capital from Ghana, and his father from Sierra Leone, before relocating to Canning Town aged 11.
He's set to appear as the Gunslinger in Stephen King's hugely-anticipated Dark Tower.
