 First Star Trek production to officially establish that Kirks  middle name is Tiberius and Sulus first name is Hikaru. Tiberius  had been mentioned in an episode of the animated Star Trek series,  however by this point the cartoon was no longer considered  canonical. No first (or last) name is offered for Uhura in this  film, which is taken as confirmation of Gene Roddenberry (qv)s  contention that she has no other name.
