Interviewer: "There's a great deal of
writing in the Star Trek movement which compares the relationship
between Alexander and Hephaistion to the relationship between Kirk and
Spock - focusing on the closeness of the friendship, the feeling that
they would die for one another..."
Gene Roddenberry: "Yes,
there's certainly some of that - certainly with love overtones. Deep
love. The only difference being, the Greek ideal... we never suggested
in the series... physical love between the two. But we certainly had
the feeling that the affection was sufficient for that, if that were
the particular style of the 23rd century."
