It was 10 a.m., adoring union members had already roughly mobbed their president, Fran Drescher, and the group was rising by the minute.

Outside Netflix workplaces in Hollywood, a festive, buoyant temper had taken over the intersection of Sunset Boulevard and Van Ness Avenue. It was a staff’ strike, to make certain. But as smiling protesters eagerly joined in chants and high-fived their picket indicators, it felt a little bit like a summer season Friday avenue celebration. One with just a few well-known company.

“We’re told that we should just be so grateful to get to do what we love to do — but not being compensated, not being protected while they are profiting off of our work,” stated Amanda Crew from HBO’s “Silicon Valley,” who walked the picket line with Dustin Milligan from “Schitt’s Creek.”

“That’s the myth of the actor: You’re doing art so you should just be so grateful because you’re living your dream. Why? Do we do that to doctors? We bring so much joy to people by entertaining them,” Crew added.

It was the primary of what could possibly be many days of marching for actors, who picketed at areas throughout the nation. They chanted, “Actors and writers unite!” as they marched alongside a brief block in Times Square the place Paramount conducts enterprise; they handed out bottles of chilly water and cans of La Croix exterior 30 Rockefeller Plaza in Midtown Manhattan; and so they bounced their picket indicators to the sounds of Jay-Z’s “Dirt Off Your Shoulder” because it blared from a speaker in Hollywood.

A day earlier, the Hollywood actors’ union, generally known as SAG-AFTRA, approved a strike for the primary time in 43 years, becoming a member of forces with writers, who walked out in May.

“There’s a renewed sense of excitement and solidarity,” stated Alicia Carroll, a strike captain for the Writers Guild of America. “Writers have been out here for upwards of 70 days. It’s been a while and it’s hot. People are tired. So this is a confidence boost that we’re not alone in the industry in terms of issues.”

The actors and writers have been unable to comply with new contracts with the Alliance of Motion Picture and Television Producers, which represents main studios and streamers. Pay is a central issue, however the negotiations round compensation have been difficult by the emergence of streaming providers and the rise of synthetic intelligence.

Actors, together with Ms. Drescher, the president of their union, have forged the second as an inflection level, arguing that all the enterprise mannequin for the $134 billion American film and tv enterprise has modified. They say their new contract must account for these modifications with numerous guardrails and protections, together with elevated residual funds (a kind of royalty) from streaming providers. They are additionally fearful about how A.I. could possibly be used to copy their work: scripts within the case of writers and digital replicas of their likenesses for actors.

Hollywood corporations have insisted that they labored in good religion to achieve an inexpensive deal at what has additionally been a tough time for an business that has been upended by streaming and continues to be coping with the lingering results of the pandemic.

“The union has regrettably chosen a path that will lead to financial hardship for countless thousands of people who depend on the industry,” the studio alliance stated in an announcement after SAG-AFTRA introduced the strike.

On Friday, writers stated they had been heartened to be joined on the picket strains by actors, a lot of whom have been marching with them for months within the black-and-yellow T-shirts which have change into one thing of a uniform. It is the primary time since 1960 that actors and screenwriters have been on strike on the identical time.

WGA leaders have shared picket line recommendation: Bring loads of sunscreen and set a timer to reapply, be careful for site visitors. But some actors had been already veterans.

“I have not been to a picket without SAG-AFTRA members there. Sometimes they have even outnumbered us here in the east,” stated Lisa Takeuchi Cullen, a vice chairman of the Writers Guild of America, East. “They have been our stalwart supporters and comrades, and we intend to reciprocate.”

“Suddenly,” she added, “the sleeping giant has awaked.”

Indeed, among the union’s most outstanding members took to the streets Friday and drew discover because the afternoon wore on. Jason Sudeikis confirmed up at 30 Rock; Susan Sarandon went to the Flatiron neighborhood, the place picketers focused Warner Bros. Discovery; and Sean Astin marched exterior the Netflix workplaces in Los Angeles.

“Our careers have been turned into gig work,” Mr. Astin stated over a refrain of frenetic honks of help from passing vehicles. “It’s not just that we’re not going to take it any more — we actually can’t take it anymore.”

An animated Ms. Drescher had arrived at the same location earlier in the day and was met with an exuberant crowd that wrapped itself around her.

“This strike and this negotiation is going to impact everybody, and if we don’t take control of this situation from these greedy megalomaniacs, we are all going to be in threat of losing our livelihoods,” Ms. Drescher stated.

“I’m not really here for me as much as the 99.9 percent of the membership who are working people who are just trying to make a living to put food on the table, pay rent and get their kids off to school,” she added. “They are the ones that are being squeezed out of their livelihood, and it’s just pathetic.”

Shara Ashley Zeiger, an actor, brought her 2-year-old, Lily, to the picket in front of NBC’s offices in New York. A sign protruded from her daughter’s stroller. Lily played with her food — and a tambourine.

“The effects of this deal directly affect my daughter and my family,” Ms. Zeiger said.

She added: “I had had a role on a project that was on a streamer, and their deal was they didn’t have to pay me residuals for two years. And it was in the middle of the pandemic.”

Thousands of miles west in Los Angeles, Evan Shafran, an actor who had taken it upon himself to put together an hourslong playlist for the strike, wondered whether he might eventually need to apply for Medi-Cal, the state’s medical assistance program. He was able to string together enough work to pay for health insurance this year, but he could not be sure how things would pan out in the future.

And last week, Mr. Shafran said, his car was stolen. But he took an Uber from his home in the San Fernando Valley to the Netflix offices anyway.

“I spent $100 to come protest today even though I’m out of work,” he said. “I need to be out here.”
