LOS ANGELES (Reuters) -Negotiators representing Hollywood actors are considering a new proposal that major studios described as their "last, best and final offer" to end a four-month-long strike, the SAG-AFTRA union said on Saturday. SAG-AFTRA members walked off the job in July to demand higher compensation in the streaming TV era plus protections around the use of artificial intelligence (AI) and other gains. The Alliance of Motion Picture and Television Producers (AMPTP), which represents Walt Disney, Netflix and other companies, presented its latest offer on Saturday, SAG-AFTRA leadership said in an update to members.
