Hollywood actors walk out of Oppenheimer premiere as strike action starts – video report

The union representing Hollywood actors formally announced a strike on Thursday, joining writers who have already been on strike for weeks. The action by the Screen Actors Guild-American Federation of Television and Radio Artists (Sag-Aftra), which began on Friday, marks the first time in 63 years that Hollywood writers and actors are striking simultaneously.

Sag-Aftra has said the industrial action is being held over pay, conditions and concerns over the use of artificial intelligence. The simultaneous strikes are expected to halt the majority of Hollywood's film and TV production, and have a significant impact on the Los Angeles economy
