4. William Shatner
William Shatner should be in everything. The original Captain James T. Kirk (the T stands for Tiberius by the way that's an extra thing 'you must know' for free) has developed somewhat of a cult following and Trekkers have an endearing and enduring loyalty to him. Whether it is his slightly unsatisfactory on screen death in Star Trek Generations, his eccentric personality or maybe his music career, Bill Shatner has got something that we Trekkers love. Given just half a chance of getting him back aboard the bridge of the Enterprise most of us would sell our own grandmothers in a flash to make it so. He is unfairly maligned for his unique.... vocal..... .....delivery. However this trait is much exaggerated and other aspects of his on and off screen persona have been roundly made fun of over the years, quite often by Shatner himself. This all detracts from the fact that he is a very good actor. The Star Trek films and most recently Boston Legal show a very talented actor, equally comfortable with action and wry humour.
