LOS ANGELES (Reuters) - Former “Star Trek” crew member George Takei married his longtime boyfriend on Sunday in a Los Angeles ceremony that paid homage to the actor’s Japanese heritage.

Takei, 71, tied the knot with his business manager, Brad Altman, 54, as some of his “Star Trek” castmates looked on, including best man Walter Koenig (“Chekhov”) and matron of honor Nichelle Nichols (“Uhura”). Takei played Mr. Sulu in the 1960s sci-fi series and in subsequent movies.

Nearly 200 people attended the Buddhist ceremony at the Japanese American National Museum in downtown Los Angeles. The couple wore matching tuxedos -- white jackets and shirts, with black trousers and bow ties.

The event came three months after California followed Massachusetts’ lead and allowed same-sex weddings. Last month, comedian Ellen DeGeneres married Australian actress Portia de Rossi in Beverly Hills.

Takei, who was interned along with his family and 120,000 other Japanese-Americans during World War Two, is a longtime human rights activist. After the California Supreme Court struck down a ban on same-sex marriage in May, Takei and Altman were among the first gay couples to get a marriage license. They have been together more than 21 years.
