Star Trek III: The Search for Spock (1984)
Star Trek III: The Search for Spock is the Star Trek film that exists primarily to undo the consequences of the previous Star Trek film. Christopher Lloyd plays the Klingon commander Kruge.
Actor: DeForest Kelley
DeForest Kelley spent the 1950s playing western villains, including in Gunfight at the O.K. Corral, before Star Trek gave him Leonard McCoy.
McCoy functions as the emotional counterweight to Spock’s logic, and the arguments between the two are the show’s most durable dynamic.
The line I’m a doctor, not a bricklayer recurs in variations across the series and became a template. He continued in the role across six films and had a brief appearance in The Next Generation’s first episode.
