Nurith NupurMark Lenard as Sarek
With the huge history of Star Trek that span over 1966 to 1991, Mark Lenard can arguably be associated to all of it. He first had an appearance in the season 1 as a Romulan Commander and in the following season, he played the role of Spock’s father. He later went on to play the same role in the first 5 Star Trek movies as well. He, unfortunately, passed away in 1996.
