Leonard Nimoy has announced that he is to retire from acting. The actor, 79, is best known for playing the Vulcan Spock in the hugely successful ‘Star Trek’ series.
He appeared in last year’s big screen reboot of the franchise, but has now vowed to call it a day. He said: “I love the idea of going out on a positive note. I’ve had a great, great time. Since ‘Star Trek’ began, I’ve never had to worry about where the next job was.”
While Nimoy will forever be known for playing Spock, he has also had a varied career as a singer, poet, writer and director. (He helmed two ‘Star Trek’ films in the ’80s, as well as 1987′s ‘Three Men and a Baby.’)
We take a look at what the other ‘Star Trek’ actors have been up to since they left the USS Enterprise.
William Shatner
Unlike Nimoy, Shatner never got the chance to reprise his role as Captain Kirk in last year’s blockbuster. However, he has enjoyed the biggest success out of the Enterprise crew – starring in number of Hollywood movies, including ‘Miss Congeniality’. He also enjoyed great success on the small screen, appearing in 100 episodes of ‘The Practice’ and its spin-off show ‘Boston Legal’, alongside James Spader. He won a Golden Globe in 2005 for his performance on the latter.

DeForest Kelley
He kept busy with roles on the small screen following the cancellation of the ‘Star Trek’ TV series, in which he played the sarcastic Dr Bones. He sadly passed away in 1999 from stomach cancer.
James Doohan
As Scotty, he ensured that if anyone uttered the words ‘I just can’t do it Captain,’ it would be done with a slightly rubbish Scottish brogue. His acting career after ‘Star Trek’ wasn’t a huge success, and he passed away in 2005 at the age of 80.

Nichelle Nichols
Nichols has had plenty to do since she stopped playing Communications Officer Nyota Uhura. She had a recurring role in TV show ‘Heroes’ and has lent her vocal talents to many animated series, including ‘Batman’, ‘Star Trek’ and ‘Spider-Man’.
George Takei
To fans of ‘Star Trek’, George Takei will always be Sulu. However, to fans of reality TV, George Takei will always be the man who came third on ‘I’m a Celebrity… Get Me Out of Here!’ He married his long-time boyfriend in 2008, and also appeared in ‘Heroes’.
Walter Koenig
Following his exit from the show (playing Chekov), Koenig has worked steadily – whether it’s making appearances on programmes like ‘Babylon 5’ or writing books about his experiences on ‘Star Trek.’
