Actor Michael Sheen has stated that he finds it "hard to accept" non-Welsh actors portraying Welsh characters.
The Hollywood star was asked by The Telegraph if actors should take on roles they cannot relate to personally.
Some have noted that Sheen has played characters like Kent-born David Frost and Tony Blair, who was born in Edinburgh.
He claimed, however, that the cast and crew of his newest drama, Best Interests, inspired him to take this position.
The Port Talbot-born actor called it "striking" because he had rarely seen it before that several people with disabilities worked on the project, which centers on a family whose child has cerebral palsy and experiences a life-threatening seizure.
Sheen was prompted by this to wonder if actors could successfully assume identities that were not their own.
It's difficult for him to accept that non-Welsh actors are portraying Welsh characters, he admitted. ".
However, the actor went on to clarify that this viewpoint was not "particularly on a point of principle".
The same goes for actors who come from "quite privileged backgrounds," according to Sheen, who claimed that not many of them are "particularly compelling" when playing characters from working-class backgrounds.
He questioned, "If you haven't gone through something, you know, the extreme example is, well, if you haven't killed someone, can you play a killer?".
However, Twitter users have accused the actor of having double standards because he has played many non-Welsh roles.
Some people said there should be a discussion on this subject.
There is some history to this discussion. When playing DCI Taff Jones in the true crime series White House Farm in 2020, This is England star Stephen Graham, who was born in Kirkby, Lancashire, encountered some criticism.
With Graham playing the lead role as a Welsh detective, the drama portrayed the actual story of the White House Farm murders, which occurred in Essex in 1985.
His portrayal of the police officer's Welsh accent, however, drew criticism; one Twitter user described it as "a cross between Russian and Jamaican.".
Sheen talked about a variety of non-Welsh roles in addition to actors.
The Prince of Wales title, in his opinion, ought to be abolished.
"I find it to be ridiculous. It's absurd," he said.
"I don't see why the title should go on.
Without a doubt not with a non-Welsh person. ".
The "majority view," he did add, was that this was not the case.
