LOS ANGELES — James Darren, a teen idol who helped ignite the 1960s surfing craze as a charismatic beach boy paired off with Sandra Dee in the hit film “Gidget,” died Monday at 88.

Darren died in his sleep at a Los Angeles hospital, his son Jim Moret told news outlets.

Moret told The Hollywood Reporter that Darren was supposed have had an aortic valve replacement but was too weak for the surgery. “I always thought he would pull through,” his son told the entertainment trade, “because he was so cool. He was always cool.”

In his long career, Darren acted, sang and built up a successful behind-the-scenes career as a television director, helming episodes of such well-known series as “Beverly Hills 90210” and “Melrose Place.” In the 1980s, he was Officer Jim Corrigan on the television cop show “T.J. Hooker.”

But to young movie fans of the late 1950s, he would be remembered best as Moondoggie, the dark-haired surfer boy in the smash 1959 release “Gidget.” Dee starred as the title character, a spunky Southern Californian who hits the beach and eventually falls in love with Moondoggie.

“I was in love with Sandra,” Darren later recalled. “I thought that she was absolutely perfect as Gidget. She had tremendous charm.”

The film was based on a novel that a California man, Frederick Kohner, had written about his own teenage daughter and helped spur interest in surfing — one that influenced pop music, slang and even fashion.

For Darren, his success with teen fans led to a recording contract, as it did with many young actors at the time, among them Tab Hunter and Annette Funicello. Two of Darren’s singles, “Goodbye Cruel World” and “Her Royal Majesty,” reached the Top 10 of the Billboard Hot 100 chart. (“Goodbye Cruel World” also appeared in Steven Spielberg’s 2022 semi-autobiographical film, “The Fabelmans.” ) Other singles included “Gidget” and “Angel Face.”
