Sir Anthony Hopkins has described himself and fellow actors as “pretty stupid” and said he doesn’t think it’s worth asking actors’ viewpoints on big issues.

In a discussion with Meet Joe Black co-star Brad Pitt for Interview Magazine, Hopkins also revealed he rarely watches “green screen films”, despite his roles in several blockbuster franchises.

Hopkins told Pitt he is often asked to express his viewpoint on big developments in the movie industry or in the world as a whole.

“I don’t have any opinions,” he said. “Actors are pretty stupid. My opinion is not worth anything.

“There’s no controversy for me, so don’t engage me in it, because I’m not going to participate.”

The 81-year-old is currently promoting his role as Pope Benedict XVI in the Netflix drama The Two Popes, in which he appears alongside Jonathan Pryce as Pope Francis.

Hopkins said he is “not a great fan of going to movies anymore”, but did say he had found the time to watch Pitt’s performance in Once Upon a Time in Hollywood, for which he is tipped to finally win an acting Oscar.

“I’m not great at going to see the green screen films,” Hopkins added.

“I’ve been in a few of them and they’re fun, but they don’t grab me. I’m a bit too old for that.”
