Over the past several decades, William Shatner has been criticised by some of his Star Trek co-stars, but most notably by Mr Sulu actor George Takei. Tensions between the two go all the way back to filming the original TV show in the 1960s. This included a time the Captain Kirk star allegedly had production shut down for a half a day because he had contractual approval of a photographer on the sound stage, dismissing one he didn’t approve of.

On another occasion, Shatner accused Takei of being a “loose cannon” when shooting their sword fight in The Naked Time, adding in his book Star Trek Memories: “I really do think that some small part of [Takei] was upset that he didn’t get to run me through.”

Their feuding even continued through the Star Trek movies, with the Sulu actor initially resisting playing the role in The Final Frontier, after hearing Shatner would be directing. He said in 2014: “I have a lot of friends in my Star Trek cast, except for one. We had a friendly tension going between us. And I thought, the best thing to do with Star Trek V, which was being directed by him, was to demur from doing it.”

Now as Shatner, 91, promotes his new book Boldly Go: Reflections on a Life of Awe and Wonder, both he and Takei, 85, have lashed out at each other once again.

Takei said on The Graham Norton Show this evening: “You are the last chat show host to be allowed to ask that question as it has become so tiresome to talk about. When Bill has a book to sell he needs publicity and accuses us of using him. My subject is more substantial and important. He is a cantankerous old man and I will not talk about him anymore. I vow that this is the very last time I talk about him.”
