There are so many amazing guest actors in Star Trek that I still am surprised to find after all these years, and seeing just about every episode. Most recently, I noticed the wonderful Carolyn Seymour, who plays the Romulan Commander in TNG's "Contagion," plays the Romulan commander(and does an incredible job) in TNG's "Face of the Enemy. I noticed it was her playing Mrs. Templeton in Janeway's holonovel. When I looked her up, I realized she also plays the space program director in TNG's "First Contact." Another one I noticed recently was Alan Scarfe, who plays the Romulan commandant in "Birthright Part II," also plays the cold, creepy Commander in Voyager's "Resistance," a good, but not so well known episode which also features Joel Grey. What are some of the guest actors that you were pleasantly surprised to recognize?
