The Star Trek legend George Takei will be accompanied by several of his former co-stars when he marries his longtime boyfriend Brad Altman in a civil ceremony this autumn.
The actor - famous for his role as helmsman Mr Sulu - has chosen Walter Koenig, who played Pavel Chekov, to be his best man and Nichelle Nichols, better known as Lieutenant Uhura, as the matron of honour.
Leonard Nimoy, who played the half-human, half-Vulcan science officer Mr Spock, will also attend the nuptials in Los Angeles on September 14.
Conspicuously absent from the guest list is William Shatner, who played Captain Kirk in the 1960s series. The pair reportedly fell out during filming of the television show over the way Shatner treated fellow cast members.
Takei, 71, announced that he would marry his partner of twenty years when the Californian supreme court lifted a ban on same-sex marriages last month.
He told People.com this week that he hoped the ceremony would be more romantic than the proposal.
"We knew that the Supreme Court was going to be coming down with their ruling. (We'd heard) that it was probably going to be positive. So I was planning on asking Brad to get married," he explained.
"We were at home in the kitchen and we had the TV going, and when the word came down suddenly Brad got on his knees in front of me. And I said, 'What are you doing?' He said, 'George, will you marry me?' I said, 'Yes. You beat me to it. I meant to ask you.'"
He also revealed details of the guests.
"The best man is my colleague from Star Trek, Walter Koenig, who played Chekov, and the matron of honour is Nichelle Nichols. And Leonard (Nimoy) and his wife Susan are on the (guest) list."
His partner Mr Altman diplomatically said the reason Shatner may not be invited was due to number limitations.
"We have only 200 seats," he told AP radio this week. "Our contact list has, like, 3,500 names, so we have to whittle it down and I don't know if William Shatner is going to make the cut."
