The animated STAR TREK series brought back the voice talents of almost all the original
regular cast members with the exception of Chekov. The production studio made an extraordinary
effort to capture the likeness of the animated characters' live action counterparts. Because
the animated art form in almost unlimited, such non-human characters as Lieutenant M'Ress and
Lieutenant Arex could be regular crewmembers. Lieutenant Arex especially, a being with three-arms and three legs,
could never have been done in a live action series of the 60's or 70's.
