Richard Chamberlain – Beverly Hills, 87

Richard Chamberlain may be 87 years old now, but he was only in his 20s when he became a fan-favorite playing the titular role in Dr. Kildare back in the ’60s. Surprisingly, he hasn’t retired just yet and has been active through all these decades, securing at least 86 credits, as per his IMDb page.

Some of Chamberlain’s other distinguished appearances were in Shōgun, The Thorn Birds, and The Bourne Identity. The most recent appearance that he made was that of Igor in Finding Julia in 2019. Perhaps his $20 million fortune has him covered for the rest of his life.
