LOS ANGELES (AP) — Hollywood directors on Tuesday reached a four-year tentative contract agreement with studios and streaming services.

The deal struck between the Directors Guild of America and the Alliance of Motion Picture and Television Producers came four weeks after talks began.

The talks were the first under new DGA President Christopher Nolan, who took the job in September.

Along with similar four-year deals — longer than the industry three — ratified in recent weeks by unions representing writers and actors, the DGA agreement adds to the likelihood of long-term labor peace despite many other industry upheavals.

The collective bargaining agreement must still be approved by the guild’s national board, and no details on the terms will be released until then, the DGA said in a statement. It then must be ratified by the guild membership. But tentative agreements generally win approval at both stages.

The directors’ previous contract had been set to expire June 30.

The AMPTP said in a statement that it was pleased to help achieve “a fair deal that helps advance a stable and successful entertainment industry.”
