In an interview with The Guardian, Takei called Shatner a "cantankerous old man" when asked about the feud itself, as well as Shatner's claim that Takei has been using his name to promote himself.

Takei and Shatner first worked together over 50 years ago.

Some members of the Star Trek cast have remembered Shatner having a big ego on the set of the show. Earlier this year, Shatner spoke about finding out that cast members had an issue with him from co-star Nichelle Nichols before her death. He told USA Today that his reaction was "total shock."
Takei said everyone got along except Shatner.

After explaining that two of his co-stars—Nichols and Walter Koenig—were in his wedding party in 2008, Takei was asked if anyone was friendly with Shatner. “No, none of us," he said.
That said, Leonard Nimoy, who played Spock and died in 2015, had been known to be close to Shatner at times, but their relationship wasn't always solid.

He said he didn't want to discuss Shatner...
Kathy Hutchins / ShutterstockThe Guardian story notes that Takei was "reluctant" to talk about Shatner.
"I know he came to London to promote his book and talked about me wanting publicity by using his name. So I decided I don’t need his name to get publicity," Takei explained. "I have much more substantial subject matter that I want to get publicity for, so I’m not going to refer to Bill in this interview at all." Elsewhere in the interview, Takei discussed the musical he's starring in and his experience in a Japanese internment camp during World War II.
...but realized he was commenting on him anyway.
Steve Edreff / ShutterstockTakei realized that he was commenting on his former co-star by saying that he didn't want to talk about him. "Although I just did," the actor continued. "He’s just a cantankerous old man and I’m going to leave him to his devices. I’m not going to play his game."
The publication asked if Shatner was cantankerous as a young man, to which Takei replied, "He was self-involved. He enjoyed being the center of attention. He wanted everyone to kowtow to him."
Shatner accused his co-stars used him for publicity.

"Sixty years after some incident, they are still on that track. Don't you think that's a little weird?" Shatner said of his Star Trek co-stars criticizing him (via Deadline). "It's like a sickness. I began to understand that they were doing it for publicity."
Of Takei specifically, Shatner said, "George [Takei] has never stopped blackening my name. These people are bitter and embittered. I have run out of patience with them. Why give credence to people consumed by envy and hate?"
Shatner and Takei shared one amicable moment.

Takei took part in Comedy Central's roast of Shatner in 2006. After telling jokes about his co-star, Takei concluded, "Despite our tensions, I'm honored that you invited me to be here with you tonight. I can finally say what I have waited 40 years to say: [Expletive] you and the horse you rode in on." They actors then embraced in a hug that was, unfortunately, not a sign of a warmer friendship to come.
