While workers across the entertainment industry waited for word of the outcome, no agreement had been announced as of late Friday, the 144th day of the strike.

Walt Disney CEO Bob Iger, Netflix Co-CEO Ted Sarandos, Warner Bros Discovery CEO David Zaslav and Donna Langley, chairman of Comcast's NBCUniversal Studio Group, took part in the talks with the Writers Guild of America (WGA) for a third straight day.

Representatives for the WGA and the Alliance of Motion Picture and Television Producers (AMPTP), which represents the studios, had no comment.

While the two sides met, union members turned out in large numbers in response to an appeal from WGA negotiators on Thursday to flood picket lines outside the studios.

In the crowd outside Netflix on Friday was "Mad Men" creator and writer Matthew Weiner, who like others voiced optimism that the recent talks signaled progress was being made.

"I'm hopeful," Weiner said of the possibility that the strike could be coming to an end. "I would like to go back to work and I would like to start mending these relationships."

Roughly 11,500 WGA members walked off the job in May to demand higher pay and residuals in the streaming TV era plus limits around the use of artificial intelligence (AI).

Producer and WGA member Al Septien, also picketing outside Netflix on Friday, said he wanted to get back to work, but only under the right terms.

"We've been out here a long time. We don't want to fold for a less-than-fair and good contract for the writers," he said.

The SAG-AFTRA actors union also is on strike after walking off the job in July.
