In a new interview, the 90-year-old actor said that he’s never watched an episode of the sci-fi series, which originally ran from 1966 to 1969. On the show, William played Captain James T. Kirk.
“I have never watched ‘Star Trek’,” William shared with People. “There are many episodes I don’t know, there are some movies I don’t know.”
However, William did say he watched the 1989 movie Star Trek V: The Final Frontier, but that’s only because he directed the movie.
“I directed one of the movies — No. 5 — I had to watch that one,” he said.
William then explained why he’s never watched any of his Star Trek performances.
“It’s all painful because I don’t like the way I look and what I do,” William added.
