In 1975 he toured with and played the title role in the Royal Shakespeare Company's "Sherlock Holmes". A number of authors have perceived parallels between the rational Holmes and the character of Spock, and it became a running theme in "Star Trek" fan clubs. "Star Trek" writer Nicholas Meyer said that "the link between Spock and Holmes was obvious to everyone." Meyer gives a few examples, including a scene in "Star Trek VI: The Undiscovered Country," in which Spock quotes directly from a Doyle book and credits Holmes as a forefather to the logic he was espousing. In addition, the connection was implied in "Star Trek: The Next Generation", which paid homage to both Holmes and Spock.
