Though she only stayed on the Enterprises for a brief time she was still remembered by the fans for a really long time. Janice Rand acted as Captain Kirk’s personal assistant and often seen as some in a need of rescue. Sadly it only took her 8 episodes before she lost her contract but ever since then she has been seen acting in numerous movies.
Michael Dorn as Lt. Worf
No one has contributed to the series as much as Michael Dorn did with his character Worf. He made his appearance in the very first episode of the series Star Trek: The Next Generation. Since the conclusion of the series he also worked on Deep Space Nine. He has acted on an impressive 272 Episodes of the show and on top of that 4 movies too. To this day he can be seen acting in movies and tv shows.
Whoopi Goldberg as Guinan
Although we know her know for her talk show, The View, there was once a time when Whoopi was acting full time of Star Trek: The Next Generation. She was a bartender and also played a kind of therapist role for Captain Picard. One can say that she has garnered more success than any of her Star Trek co-stars. She has since won an Emmy award, a Grammy and an Academy Award for best actress. Talk about success.
Brent Spiner as Lt. Commander Data
When Bret Spiner was first chosen for the role of Data in 1987, no one imagined that he would be delivering such a character-defining performance. He too wouldn’t have guessed that he will go in to do this character for the next 15 years of his life. Since the show’s run between 1987 to 1993, he was only absent in one episode. Now he can be seen working in theatre and making music.
Denise Crosby as Lt. Tasha Yar
This celebrity is well known for her role as Lt. Tasha Yar from the very first episode of The Next Generation. Though she had to be removed because of issues with payment. But this didn’t stop her from making her way back to the series, this time around playing the role of her former character’s daughter. Later she went on to do several shows and films but nothing matched the fame she received during the run of Star Trek.
Colm Meaney as Miles O’Brien
When we think about moving up in ranks only one name comes to mind Miles O’Brien, as he was seen as a random helm worker in the first episode and only had a small role here and there with a couple of lines thrown around. But Everything change when he made an appearance in The Deep Space Nine where he played the main character! Now he can be seen working in movies and short films.
