Few characters are as closely tied in our collective pop culture memory as William Shatner and Captain Kirk. From the way Shatner delivered his lines with dramatic pauses to the swagger that he gave to each of Kirk's romantic alien conquests, Shatner truly made Kirk his own. He even went on to co-write James T. Kirk novels set in what is called the "Shatnerverse," where Captain Kirk is brought back to life after his death in Star Trek: Generations.
