Hollywood actors officially went on strike Thursday, July 13, as the Screen Actors Guild-American Federation of Television and Radio Artists (SAG-AFTRA) announced a strike after talks with the Alliance of Motion Picture and Television Producers (AMPTP) broke down. The news comes two months after the Writers Guild of America (WGA) went on strike on May 2, marking the first time since 1960 that actors and writers have gone on strike simultaneously. Hollywood is expected to be effectively shut down until the two unions reach a fair agreement with AMPTP, which represents the major studios and streaming services.

"What is happening to us is happening to all labor sectors," SAG-AFTRA President Fran Drescher said at a press conference announcing the strike. When employers put Wall Street and greed first and forget about the essential contributors that keep the machine running, we are in trouble, and that is exactly what we are experiencing right now. ...... The gravity of this move is not understood by me, the bargaining committee, or the board members who unanimously voted to go on strike. This is a very serious matter affecting thousands, if not millions, of people throughout this country and around the world."

Last month, more than 300 SAG-AFTRA members, including Meryl Streep, Jennifer Lawrence, Rami Malek, Quinta Branson, Julia Louis-Dreyfus, Amy Schumer, and Amy Poehler, signed a letter to the union's bargaining committee, stating that "the union is committed to a fair and equitable trade agreement with the union, urging them not to accept a deal that does not meet all of the union members' demands. In addition to suspending work on scripted films and television series, actors will not be allowed to promote their film and television work through premieres, interviews, or social media accounts during the strike period.

Prior to the strike, several celebrities shared their support while attending their final movie premieres in the near future. At the London premiere of "Barbie" on Wednesday night, Margot Robbie told Sky News that she "absolutely" supports the SAG-AFTRA strike. She added, "I support all unions, and I'm part of SAG, so I absolutely support it."

On Thursday morning, the highly anticipated film "Oppenheimer" premiered in the UK. In footage from the premiere, director Christopher Nolan said of their exit: "They are out writing picket signs because of the supposed impending SAG strike.

Over the weekend following Thursday's announcement, many A-listers shared their support for the strike on social media through passionate calls for solidarity and candid posts sharing their experiences as actors. Kimiko Glenn, actress of "Orange is the New Black," opened up about her experience with the pay gap while working on the Netflix hit "Orange is the New Black," saying that many of the actors on the show were not paid well enough to quit their side jobs. 'They were all still bartenders. They were all still working on the side. They were fucking famous, internationally famous, and they were the kind of people who couldn't get out, but they had to keep their side jobs.

In addition to social media posts, several clips have been posted of celebrities picketing Hollywood and voicing their support. See below for clips and posts from celebrities including Jane Fonda, Margot Robbie, Jamie Lee Curtis, and Cynthia Nixon.
