Star Trek is one of the most popular science fiction TV series of all time. Three seasons aired from 1966 until 1969 and the series was later continued on the big screen for a total of 12 feature-length movies.
The character of "Captain Kirk" is William Shatners best-known and most popular role. He played the steadfast and brave captain for three years on "Star Trek" and, of course, reprised his role for all of the movies that followed in the years after...
Even after "Starship Trek" Shatner remained a popular film and TV actor. The younger audience probably knows him from films such as "Miss Congeniality" and "Dodgeball", or from his great run as "Denny Crane" from 2004 until 2008 on "Boston Legal".
Leonard Nimoy became world famous as a "Mr. Spock". He played the role for three seasons on the TV show and also in all of the Star Trek movies.
In 2013, Nimoy reprised his role of "Mr. Spock" once again in the new "Star Trek" film. He also had a guest appearance in "The Big Bang Theory". Unfortunately, he died in February of 2015 from chronic obstructive pulmonary disease (COPD).
DeForest Kelley was originally supposed to portray the role of "Mr. Spock", but became "Dr. Leonard McCoy", whom he played in the series and in the movies.
The 1991 film "Star Trek VI: The Undiscovered Country" was Kelley's last appearance in front of a camera. He quit the film business and lived out his life until 1999, when he passed away. The actor had suffered from stomach cancer - a fight he eventually lost at the age of 79...
James Doohan was known as "Lt. Montgomery Scott" during the mid-1960s. He described his character as "99 percent James Doohan and one percent accent..."
After Star Trek hardly any other roles were offered to Doohan, which is why he appeared still mainly as "Scotty" in the Star Trek films. He died in 2005 after a long illness.
George Takei played the character of "Lt. Hikaru Sulu". Before his time on Star Trek he appeared mainly in remakes of Japanese horror films, like Godzilla for example.
At the beginning of the 70's, Takei started taking an interest in politics and became quite active - he eventually returned to acting and now is a guest star from time to time on a variety of shows. He mainly does work as a voice actor today...
Nichelle Nichols played "Lt. Nyota Uhura". She was one of the first African-American women in a major television series and was thus a beacon for the civil rights movement.
After the end of Star Trek, Nichols started working on a special project with NASA to recruit minority and female personnel for the U.S. space agency. Nichols is 84 years old by now and still acts. She most recently appeared on the TV series Downward Dog.
With the beginning of the second season, Walter Koenig played the "Pavel Andreievich Chekov" in seasons two and three, as well as in all of the movies.
After his role as "Chekov", Koenig had a recurring role as Psi Cop Alfred Bester on the television series Babylon 5. He was a "Special Guest Star" in twelve episodes and, at the end of the third season. Later, he also gave acting lessons at the University of California, Los Angeles.
Majel Barrett played "Christine Chapel", the nurse aboard the "Enterprise". She was also married to the creators of the series, Gene Roddenberry.
After Star Trek she produced her own shows, like the science fiction series Andromeda. Barrett died in 2008 from leukemia at the age of 76.
Grace Lee Whitney played "Janice Rand", the personal assistant of "Captain Kirk", but left the series after eight episodes.
Whitney would later reprise her role of "Janice Rand" in the Star Trek movies. Her finale film role was in Star Trek: Of Gods and Men (2007) as "Commander Janice Rand". She died of natural causes at her home in California on May 1st, 2015. She was 85 years old.
