There has been no deal reached between the striking writers and the heads of the four major Hollywood studios as a result of a “marathon session” of negotiations that lasted more than ten hours on Thursday evening, a person familiar with the matter said.

In spite of the fact that the person requested anonymity because they were not authorized to speak publicly about the matter, more progress was made during the negotiations Thursday, the second consecutive day of intense talks between the two sides. However, a deal has not yet been reached to end the historic Hollywood work stoppage.

The Writers Guild of America negotiating committee informed members it will meet again on Friday with the Alliance of Motion Picture and Television Producers.

In the email, the Negotiating Committee said, “Your Negotiating Committee appreciates all the messages of solidarity and support we have received the last few days. Please come out to the picket lines tomorrow.”

Warner Bros. is the studio boss of AMPTP. On Wednesday, Discovery chief David Zaslav, Disney chief Bob Iger, Netflix co-chief Ted Sarandos, and NBCUniversal studio chairman Donna Langley resumed negotiations with the WGA. The two sides issued a rare joint statement after the meeting, noting their discussions would continue the following day.

At times, the two sides have rebuked each other for comments to the media. But issuing a joint statement a sign of progress?
