Star Trek: 10 Things You Didn't Know About Dr Leonard 'Bones' McCoy
6. McCoy And Spock: Kirk's Angel And Devil
Star Trek Beyond was praised by a lot of fans for nailing the chemistry between the Original Series characters, specifically Spock and Bones.
In issue 184 of Star Trek Magazine, the film's writers, Simon Pegg and Doug Jung, explained that they had a lot of fun writing scenes for these two in Beyond. Specifically, Yung liked the idea of having the emotional represented through McCoy, and the logical represented through Spock, so that the two of them could serve as the devil and angel on Kirk's shoulders, guiding him through his decisions. This is a very interesting way to look at their relationship.
It was always fun to watch Spock and Bones argue in The Original Series, and the scenes between the two of them in Beyond definitely called back to that old dynamic. They could get pretty heated at times, but it was always clear that they actually cared about each other very much.
