As BBCtv prepares for full-blown Star Trek mania in celebration of the show's 30th birthday, here's a chance to see the pilot episode that started it all. This was creator Gene Roddenberry's original concept for Star Trek - a rather more cerebral entertainment than it became in later years, with Jeffrey Hunter as Captain Christopher Pike and Majel Barrett (then Roddenberry's girlfriend, later his wife) as the chief officer.
In The Cage, Pike is lured down to the surface of Talos IV where he is trapped by the survivors of a crashed spacecraft, eager that he should father a new race with the amorous slave girl Vina. But all is not as it seems...
Another classic episode, The Man Trap, can be seen tomorrow, and the first episode of Star Trek: the Next Generation goes out on Wednesday. Radio Times celebrates Star Trek's birthday next week with a special supplement.
