Oscar-winning actor Anthony Hopkins is one of the most commercially successful artists in our round-up, with some of his acrylic paintings reportedly selling for up to $80,000 (£71.6k).
The Silence of the Lambs star began painting as a child back in the 1940s but didn't turn his hobby into a side hustle until his wife encouraged him to sell some of his work in the early 2000s. Since then, Hopkins has exhibited in Hawaii, Las Vegas, New York, London, and Edinburgh.
He says painting "keeps [his] brain functioning, and makes [him] laugh", and he spends hours in his home studio every week.
In October 2022, Hopkins launched his debut NFT art collection. Titled The Eternal Collection, the series of digital artworks sold out in under seven minutes.
