Let's be clear: Harry Mudd was not a good man. Yet, he was never in the villainous leagues of Khan or Dukat. He was simply a con man, jobbing his way through the galaxy, with a little disregard for the safety and liberties of others. We technically shouldn't love him. Technically.

The Original Series has the honor of playing 3 of Star Trek's most important alien species: Vulcan, Klingon, and Romulan.

The Original Series, Star Trek The Next Generation follows the crew of the U.S.S. Enterprise-D on their own voyage across the stars. Yet it stands on its own two feet, thanks to its incredible cast and the way it introduced and then built upon concepts and characters that would come to define the Star Trek universe for years.

If you watch Star Trek shows a lot, like I do, you start to notice some familiar faces. With decades of television shows and movies under its belt, it's only natural that the franchise has approached actors to play multiple roles over the years.
