F rom its shaky start in 1966 - it was cancelled after the first three seasons - Star Trek has grown to become the most commercially successful sci-fi series of all time, and an icon of modern pop culture. It spawned 11 movies and hundreds of thousands of fan clubs throughout the world. It even has its own language - Klingon. Fans - called Trekkies or Trekkers - would eagerly await each week's episode as the brave crew of the Starship Enterprise explored strange worlds, met new life forms and usually killed them. But it had its faults. Viewers knew that any 'new' character in an episode would not make it back from whatever planet they were visiting. The technology was limited, so all aliens has a strangely human-like appearance. But it thrived and shot its creator, Gene Roddenberry, to immortality among the stars. The newest Star Trek feature film, is already stealing box office thunder in the US. But if you don't know the first thing about the crew of the USS Enterprise, here's a quick run-down. Name: James T. Kirk Original rank: Captain Famous quote: 'Excuse me. I'd just like to ask a question... What does God need with a starship?' Original: William Shatner New: Chris Pine The American earthling who boldly commands the Starship Enterprise to go where no man has gone before. He's a good friend to his crew, and a great warrior when necessary. He is always in awe of the amazing things he finds in space, and has a deep respect for life, whatever form it might take. Name: Spock Original rank: Science officer Famous quote: 'After a time, you may find that having is not so pleasing a thing, after all, as wanting. It is not logical, but it is often true. Original: Leonard Nimoy New: Zachary Quinto The half-human, half-Vulcan is extremely logical. He doesn't like human emotions and he likes to always follow the rules. Name: Leonard H 'Bones' McCoy Original Rank: Medical officer/ Chief surgeon Famous quote: 'Why is any object we don't understand always called 'a thing'?' Original: DeForest Kelley New: Karl Urban Bones got his nickname originally as a shortening of 'sawbones', an old fashioned word for 'doctor'. But in the new movie, he gets it because he tells Kirk his wife divorced him and left him nothing but his bones. Name: Nyota Uhura Original Rank: Communications officer Famous line: 'Communications ready, sir. Communications officer as ready as she'll every be.' Original: Nichelle Nichols New: Zoe Saldana In previous series, Uhura, who comes from the 'United States of Africa', showed no romantic interest in Kirk, but has had a close relationship with Spock. But in the new movie, things are different. This is unlikely to go down well with long-time fans. Name: Montgomery 'Scotty' Scott Original Rank: Chief Engineer Famous line: 'The best diplomat that I know is a fully-loaded phaser bank' Original: James Doohan New: Simon Pegg The 'Scotty' of the all-time favourite Star Trek quote 'Beam me up, Scotty', he was the ship's engineer, constantly working mechanical miracles in the nick of time. Name: Hikaru Sulu Original Rank: Lieutenant Famous line: 'Let regulations be damned'. Original: George Takei New: John Cho Cho is carrying on Takei's important portrayal of an Asian as a 'good guy' in American cinematography: Sulu's character was one of the first to depict Asians in a positive light. Cho has taken on the character's swashbuckling heart. Name: Pavel Chekov Original Rank: Ensign navigator Famous line: 'I was never that young.' Original: Walter Koenig New: Anton Yelchin The token Russian. A young, naive, intelligent man, he was the last of the original characters to be introduced. Sometimes he stands in for Spock as science officer. His character has been lampooned for his cheesy Russian accent.
