Walter Koenig is going to be his best man and Nichelle Nichols will be his matron of honour. Bless. I love George Takei. I'm so happy for him.
I note the article says nothing about, as Wil Wheaton calls him, William Fucking Shatner. I suspect he's probably not invited. I think Leonard Nimoy was the only one of his co-stars who actually liked him.
