LOS ANGELES (AP) — Television and movie actors on Thursday voted overwhelmingly to ratify a four-year contract with studios and streaming services, a month after their union leaders negotiated a deal they say provides protections against synthetic actors created by artificial intelligence.

The ratification was widely expected and a walkout never seemed to be in the cards during drama-free negotiations, but the vote assures there will be no repeat of the 2023 actor and writer strikes that seriously shook the entertainment industry.

More than 90% of votes from members of the Screen Actors Guild-American Federation of Television and Radio Artists approved of the agreement, with about 19% of eligible voters casting ballots.

Like the Writers Guild of America, whose members approved their own contract on April 24, the actors’ new deal is for four years instead of the usual three, providing an extra layer of labor stability in the industry.

Actor Sean Astin, president of SAG-AFTRA, said in a statement that the contract “delivers meaningful gains in compensation, strengthens protections around artificial intelligence and digital identity, reinforces the long-term security of members’ benefit plans and recognizes the realities of how performers work today.”

The contract says AI performers must bring “significant additional value” over a live actor or a digital capture of them if producers are to use them. Union leaders say this and other provisions will keep use of AI actors minimal.

The Alliance of Motion Picture and Television Producers, which negotiates for a coalition of Hollywood’s major studios, streamers and production companies, congratulated the union on the ratification.

“SAG-AFTRA’s leadership brought a genuine commitment to partnership, and together with the WGA agreement, these deals demonstrate what is possible when the industry works toward practical solutions,” the alliance said in a statement.

AMPTP negotiators have been in contract talks with the Directors Guild of America since May 11. The negotiations are the first under new DGA president Christopher Nolan. That contract is set to expire June 30.
