LOS ANGELES — Hollywood's actors have voted to ratify the deal with studios that ended their strike after nearly four months, leaders announced Tuesday.

The approval of the three-year contract from the members of the Screen Actors Guild-American Federation of Television and Radio Artists was no certainty, with some prominent members voicing dissent on the deal for which the union leaders bargained.

The 78% yes result in voting that began Nov. 13 and ended Tuesday was a far cry from the near-unanimous approval and widespread enthusiasm members of the writers guild gave to the deal that ended their strike in September.

"Today we close out one of the most important chapters in recent entertainment industry history," the union said in a tweet announcing the results Tuesday evening.

But the outcome is a major relief for SAG-AFTRA leaders and an entertainment industry that is attempting to return to normal after months of labor strife. And it brings a final, official end to Hollywood labor's most tumultuous year in half a century, with two historic strikes that shook the industry.

A rejection of the agreement would have meant a return to the bargaining table and, with that, the possibility of the actors going back on strike if leaders called for it.

Those leaders had freed actors to return to work, declaring the strike over as soon as the tentative deal was struck Nov. 8. Two days later, it was approved by the guild's board with an 86% vote.

Control over the use of artificial intelligence was the most hard-fought issue in the long, methodical negotiations between SAG-AFTRA and the Alliance of Motion Picture and Television Producers, which represents studios, streaming services and production companies.

SAG-AFTRA President Fran Drescher told The Associated Press shortly after the resolution was reached that making sure AI reproductions of actors could only be used with their informed consent and compensation was a "deal breaker" in the talks.

But they did not fight hard enough for some prominent members, including actors Justine Bateman and Matthew Modine, who cited the issue as a reason to vote "no," and stoked fears many voters would follow their lead.

"I cannot endorse a contract that compromises the independence and financial futures of the performers," Modine, who ran against Drescher for union president in 2021 and was also among the board members to reject the deal, said in a statement. "It is purposefully vague and demands union members to release their autonomy.... Consent is surrender."

But many other prominent actors voiced strong support for the agreement, including Academy Award winner Jessica Chastain and Colman Domingo, who is getting major Oscars buzz this year for his performance in " Rustin."

"I believe that we have an incredible deal, I believe it's thoughtful and it's about moving the needle forward," Domingo told the AP last week. "I'm very happy with it. I voted yes."

The contract calls for a 7% general pay increase with further hikes coming in the second and third years of the deal.

The deal also includes a hard-won provision that temporarily derailed talks: the creation of a fund to pay performers for future viewings of their work on streaming services, in addition to traditional residuals paid for the showing of movies or series.

The provision is an attempt to bring payment systems in line with an industry now dominated by streaming, a reality that is almost certain to fuel more labor fights — and possibly more strikes — in the coming years.
