William Shatner has slammed his former Star Trek co-star George Takei for not inviting him to his wedding.

William says George, who played Enterprise helmsman Sulu, didn’t invite him to his nuptials because he harbours a grudge against the 77-year-old.

“The whole thing makes me feel badly,” William says in a video posted on his website. “Poor man. There is such a sickness there. It’s so patently obvious that there is a psychosis there. I don’t know what his original thing about me was. I have no idea.”

George and partner Brad Altman tied the knot on September 15. Former Star Trek stars Nichelle Nichols and Walter Koenig, who played Uhura and Chekhov, were among the attendees at the ceremony at the Japanese American National Museum.

George and Brad had previously stated that William was invited to their wedding, but he never RSVP-d.

“It is unfortunate that Bill was unable to join us for our wedding as he indeed was invited to attend,” responded George. “It is our hope that at this point he joins us in voting no on Proposition 8, which seeks to eliminate the fundamental right for same-sex couples to marry in California.”

William said he felt he never knew George when they worked together on the original TV series and later in the Star Trek films.

The Boston Legal actor also attacked George’s decision to come out later in life, saying: “Who cares? Be gay. Don’t be gay. That’s up to you, George.”
