James Darren, an actor and singer whose starring role as a California surfer in the “Gidget” movies made him one of the most popular heartthrobs of the late 1950s and early ’60s, died on Monday in Los Angeles. He was 88.

His son Jim Moret said the cause of his death, in a hospital, was congestive heart failure.

Mr. Darren, a Philadelphia native who didn’t surf and wasn’t even a particularly strong swimmer, had been a contract player with Columbia Pictures when he was cast as an aspiring surf bum in “Gidget,” which also starred Sandra Dee in the title role and Cliff Robertson as the Big Kahuna, the leader of a surfing gang.

Released in 1959, the movie told the story of a high school girl who befriends that gang in Malibu and develops a crush on Mr. Darren’s character, Moondoggie. It was a hit, and it became one of the first signs of the surfing craze that would soon include the music of the Beach Boys and the “Beach Party” films.

Mr. Darren went on to play the character in two more “Gidget” films, “Gidget Goes Hawaiian” (with Deborah Walley in the title role) and “Gidget Goes to Rome” (with Cindy Carol); land a role in the acclaimed 1961 World War II drama “The Guns of Navarone”; carve out a long career in prime-time television, including a starring role on the 1966-67 time-travel series “The Time Tunnel”; and release a number of singles and albums, first as a purveyor of lightweight pop tunes and later as a lounge singer whose repertoire consisted mostly of standards.

Before he was cast as Moondoggie, a character with a prominent singing role, Mr. Darren had never sung professionally. At first the studio considered having him lip-sync to someone else’s voice.
