A massive fire has broken out at the Warner Bros. Studios in Los Angeles County after a transformer reportedly blew, but has since been put out. 

Word of the fire began spreading on Twitter shortly before 2pm PST (5pm EST). A transformer blew and firefighters managed to contain the blaze, according to NBC Los Angeles. 

A Warner source told the Hollywood Reporter that the fire has been ruled an ‘accident.’  

One Twitter user claimed to have heard a ‘big boom’ and that their power ‘flickered’ before the sky began to fill with eerie smoke. Others claimed to have seen the lights flickering blocks away from the famous studio. 

A source told Deadline the studio’s power went out and soon after the smoke started to fill the large lot.  

The Citizen app claimed an electrical fire had broken out, but the fire department has not released an official cause. No injuries have been reported.

A single firetruck was seen pulling into the lot where a dark cloud of smoke rose into the bright blue sky. The fire is said to be contained, according to Deadline. 

A large plume of black smoke appeared to be coming from an upper floor at the studio as it billowed high above the studio’s roof. 

The lot is home to the famous Warner Brothers water tower but is no longer used to hold water, having previously been used for an emergency source in case of a fire.

The fire is one of several Hollywood heavyweights that writers have been striking in front of for weeks. 

Several high-profile actors – including Jennifer Lawrence, Meryl Streep, and Brenden Fraser – may soon also take to the streets as members of the Screen Actors Guild, which is currently negotiating its contract. 

The Oscar-winners were among a coalition of more than 300 actors who signed the addressed to SAG-AFTRA Leadership and Negotiating Committee ahead of a June 30 deadline for a contract with Hollywood studios, Rolling Stone reported.

The letter came in response to a clip SAG-AFTRA President Fran Drescher released to members, saying that negotiations had been ‘extremely productive’ and that leaders were ‘laser focused on all of the crucial issues you told us are most important to you,’ the outlet reported.

Drescher added, ‘We’re standing strong and we are going to achieve a seminal deal.’

The alliance of actors said in the response letter that ‘SAG-AFTRA members may be ready to make sacrifices that leadership is not’ amid ‘an unprecedented inflection point in our industry.’

The actor said that ‘what might be considered a good deal in any other years is simply not enough’ amid what they feel has been a long-running downward trend on the business end for talent.

‘We feel that our wages, our craft, our creative freedom, and the power of our union have all been undermined in the last decade. We need to reverse those trajectories.’

Among the actors who signed the letter, listed in alphabetical order, include Fred Armisen, Kevin Bacon, J. Smith Cameron, Neve Campbell, Glenn Close, Ariana DeBose, Julia Louis-Dreyfus, David Duchovny, Beanie Feldstein, Chelsea Handler, Neil Patrick Harris, Riley Keough, John Leguizamo, Dan Levy, Ron Livingston, Eva Longoria, Natasha Lyonne, Rami Malek,

Others who signed the letter include Debra Messing, Liam Neeson, Bob Odenkirk, Rosie O’Donnell, Patton Oswalt, Elliot Page, Keke Palmer, Busy Phillips, Amy Poehler, Zachary Quinto, Michael Rapaport, Emmy Rossum, Mark Ruffalo, Amy Schumer, Chlöe Sevigny, Fisher Stevens, Ben Stiller, Amber Tamblyn, Marissa Tomei, Jeanne Tripplehorn and Constance Wu.

The actors who signed the letter said that while they were ‘prepared to strike if it comes to that,’ they don’t want to, as it ‘brings incredible hardships to so many, and no one wants it.’
