NEW YORK -- Michael Douglas has two Oscars, a glamorous actress-wife and a home in Bermuda. Still, he was happy to get his hands dirty for his new movie, “King of California.”

The 62-year-old actor got behind the wheel of a backhoe to portray Charlie, a bipolar musician on a quest to find buried treasure in the suburbs of Southern California.

“I learned how to use the shovel, and I wanted to go out like Charlie and just dig around,” Douglas says in an interview on Parade.com. “What a feeling of power that is. It’s just amazing the damage you could do with a backhoe.”

Another first for Douglas: Spending time at Costco.

“I had never been to a Costco before, and it was incredible,”

says Douglas, who spent a few nights filming at the store.

“I’d get home at 9 o’clock in the morning and I’d pop the trunk and I had all these Hawaiian coconut drinks and bags of toys and stuff from my shopping sprees,” he said.

Douglas married Catherine Zeta-Jones in 2000. They have two children—son Dylan, 7, and daughter Carys, 4 -- and live much of the year on the island of Bermuda.

He has won two Oscars—as a producer for 1975’s “One Flew Over the Cuckoo’s Nest” and as an actor for his role as Gordon Gekko in “Wall Street.”

Douglas says a script is being developed for a sequel to the 1987 movie.
