You know Bill, I remember Cary Grant and Danny Kaye.
While the cast of the original Star Trek series and films created an iconic crew of characters that worked together, as people, the actors have famously had their share of disagreements and problems. Shatner and George Takei have had something of a feud going for years. William Shatner and Leonard Nimoy reportedly had their own issues, both working together and in the period preceding Nimoys death, though Shatner recently explained that wasnt why he didnt attend the actors funeral.
Speaking with Variety about his new documentary, Call Me Bill, William Shatner explained that when Leonard Nimoy passed away in 2015, it was sudden and unexpected. For that reason, Shatner had already made plans to attend a Red Cross Fundraiser the night before the funeral on the other side of the country. In the end, Shatner felt that the fundraiser would ultimately do more good in the world. He explained
While Shatner says that he chose not to attend the funeral now, a few years ago the former Captain Kirk said that he didnt attend Nimoy's service because it was made clear to him that he would not be welcome. Shatner says that Nimoy wasnt speaking to him in the period immediately prior to his death, though he has always said he doesnt understand why. Following the funeral, Nimoy's children have only had good things to say about Shatner.
