The industry looks set to effectively shut down after actors decided to join an existing walkout by writers.

It means many hit TV shows and movies will have to stop production, while actors will also stop promoting films they have already made.

Cox told Sky News: "It's a situation that could get very, very unpleasant. It could go on for quite some time. They'll take us to the brink and we'll probably have to go to the brink.

"So it may not be solved... until towards the end of the year."

The strike is over pay, conditions and concerns over the use of artificial intelligence (AI) - something Cox compared to the "boogeyman".

Cox, 77, familiar to millions for his role as media mogul Logan Roy, said the technology could lead to a fall in standards.

He said the strike was mainly in support of Hollywood writers because without them "we have nothing... That's why we have shows like White Lotus, like Succession..."

Scriptwriters have been striking for the last few months, seeking concessions such as higher minimum pay.

The Screen Actors' Guild decision to join them means it's the first time in 63 years both have walked out at the same time.

An estimated 160,000 performers - many of them low-level jobbing actors - are expected to take part - with no end date set.

Cox said one of the main reasons actors are striking is over the residual payments they receive when shows and films are repeated.

It is a particular concern given the growth of streaming services, which pay less for residuals than broadcast TV, and where many shows are constantly available for repeat viewing.

Cox said the system had been "failing rapidly" and these payments were vital for funding actors' healthcare.

"If our residuals go down it means our health insurance isn't going to be met," said Cox.

He added: "In a way, the streaming services have shot themselves in the foot because they've said 'oh, we're going very well on this front'.

"And when we called them to task and said 'what about our residuals, what about our money?', everything kind of closes down and... you know, it's not going to happen."

With AI now able to convincingly imitate actors' appearance and voice - a theme taken to the extreme in a recent Black Mirror episode - stars are concerned over unauthorised use of their likeness.

It is another of the reasons why they have decided to down tools.

Stars including Tom Cruise and Keanu Reeves are among those who have been the subject of widely viewed 'deepfakes'.

"One of the problems is we really don't know enough about it," Cox told Sky News.

"We don't know the extent to which it [AI] can operate. It's the boogeyman, it really is the boogeyman."

Cox added that it would be "unacceptable" if streaming services used AI to generate whole shows, saying "there would never be an original voice" and "the standard immediately drops".
