Here We Go Again
My uncanny ability to pick out voices has once again presented me with another pleasant surprise... I was watching an episode of Star Trek: The Next Generation. Season 1, Episode 26: The Neutral Zone. The Enterprise manages to run into a Romulan Warbird and established a video channel with the commander:

Does the guy on the left look familiar to you? Probably not... But his voice made me go: "No way!"

Does THIS guy on the left look familiar to you? None other than the Cardassian Dukat himself.
That's right. The Romulan on the left in the first picture is the same actor. Watching Star Trek backwards from Voyager has been nothing short of amazing... There are SO MANY people who've been in more than one series that it's insane. I even noticed that one of the very first Ferengi that Star Trek ever saw was the same actor who played Quark on Deep Space Nine, as well. It's too crazy... If I were watching Star Trek in the proper chronological order, I would probably forget that I'd seen the actors before they became popular recurring characters. It makes early Star Trek far easier to digest, heh.
