It is no secret that the world of Star Trek is a somewhat incestuous one with actors returning for more than one role. We have all had the moment of watching a character on screen thinking I know that voice, where was he/she from again? Only for the penny to drop and the realisation that they had appeared in a previous episode and, sometimes, in different series. Even in the films the legendary David Warner managed to appear in two films back to back as different characters. He played St John Talbot in the lamentable Star Trek V only to return briefly but triumphantly in the follow up Undiscovered Country as Chancellor Gorkon. Incidentally, he also returned to provide voice overs to more than one Star Trek computer game. Ethan Phillips, the lovable Neelix, played two different Ferengi characters, as well as appearing in Voyager as Neelix pretending to BE a Ferengi. Join us as we take a trek through the annals of history to see who else has shown up as more than one rubber faced creation or character. Some may surprise you and there is one actor who has appeared more often than any other, and its not who you think. Lets start with some of the more obvious ones and more on from there.
