Actor Jonathan Brandis died Nov. 12 at his home in Los Angeles. He was 27. The cause of death is under investigation. The Los Angeles County Coroner’s Office said the case had been reported as a possible suicide.

The former teen heartthrob was best known for his role as young computer whiz Lucas Wolenczek on the submarine adventure show “SeaQuest DSV.” The show ran on NBC from 1993-95.

Born in Danbury, Conn., Brandis began modeling at age 2 and was performing in TV commercials by age 5. At 6, he landed a recurring role on sudser “One Life to Live.” His family moved to Los Angeles when he was 9, and he guested on “L.A. Law,” “Who’s the Boss,” “Full House” and “Blossom.”

Brandis’ first starring film role was in “The NeverEnding Story II: The Next Chapter,” and he went on to star in 1992’s “Ladybugs” and “Sidekicks.” Playing a boy disguised as a girl soccer player in “LadyBugs,” he got a taste of the teen stardom that was to come. At the peak of his popularity, Tiger Beat magazine voted him the No. 1 dreamboat, and he topped a list of Seventeen magazine’s 10 sexiest guys.

Last year, he appeared in indie feature “The Year that Trembled,” about the Kent State U. shootings. Other recent credits include “111 Gramercy Park,” “Puerto Vallarta Squeeze” and “Hart’s War.”

He is survived by his parents.
