Although James MacArthur is widely remembered by TV audiences as Detective Dan "Book 'em, Dano" Williams, the former Hawaii Five-O costar has regained some level of anonymity in his personal life.

"I'm really not acting any more," says MacArthur, 60. "I've let my hair go white, so people don't really even recognize me much."

That's not the case in Hawaii, however. Even though the crime drama wrapped production in 1980 after 12 seasons, MacArthur and other cast members are still treated as local heroes.

"I was on the Big Island a few years ago, and I was speeding down a hill and a cop pulled me over. I gave him my license. He looked at it and looked at me and said, 'Hey, slow down. And by the way, two miles down the road, we've got one more speed trap.' Twelve years on the force counts for something."

Although MacArthur has lived in Palm Desert, California, for the past five years, his ties to Hawaii remain strong. He still has a home there, and he coproduced and cohosted a documentary special last year about the show and its positive impact on Hawaii tourism.

He's also a part owner of the second-largest senior publication in the United States, called Senior World.
