5. Majel Barret

Being the voice of the Starfleet computer in every series of Star Trek, including the first of the reboot films, isnt enough to get you on our exclusive list. Being one of only two actors to survive the pilot and appearing as 3 different characters in the Star Trek universe though, that will do it no problem. Majel Barret aka Majel Roddenberry first appeared as Number 1, the first officer of the Enterprise on The Cage. When the show was given an unprecedented second pilot though all but she and Leonard Nimoy were jettisoned. Majel returned as Nurse Christine Chapel, Doctor McCoys able assistant and unrequited lover of Spock. Her inclusion was somewhat controversial but personal life aside she became an integral and well-loved member of the crew. So much so that she even appeared in Star Trek The Motion Picture as the fully qualified Dr Chapel. When The Next Generation series came along she again provided the role voice of the Starfleet Computer, but it was her unforgettable performances as Lwaxana Troi that once again sealed her place as a Star Trek legend. Her attempted courtship with Captain Picard and his reactions to her were a great source of comic relief, but she was also capable of more dramatic outings such as admitting to the loss of a daughter she never spoke of. Majel, we salute you.
