Jason Sudeikis, Susan Sarandon and thousands of actors have joined screenwriters on Hollywood picket lines in its biggest strike in over 60 years.
Writers walked off the job in May, frustrated over pay, working conditions and a lack of protections from advances in artificial intelligence (AI).
Major films in production including the Avatar and Gladiator sequels may be affected by the shutdown.
While the strike lasts, actors cannot appear in films or even promote movies.
Brian Cox, the lead actor on HBO’s Succession, told the BBC the strike could last “until the end of the year”.
