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 Nimoy’s death, though Shatner recently explained that wasn’t why he didn’t attend the actor’s 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.
