.......by the way Jon Finch was the second choice for the role of KANE in ALIEN.......
"John Hurt was Ridley Scott's first choice to play Kane in Alien, but Hurt was committed to filming in South Africa and had to turn down the part. Jon Finch, who had risen to fame both as a theatre actor in Britain and in lead roles in Zeffirelli's Romeo And Juliet (1969), Polanski's Macbeth (1970) and Hitchcock's Frenzy (1972), stepped in. On the first day of shooting, Finch fell ill with the cameras on him, appearing to turn yellow and lifeless. Ridley Scott stopped the shot and had to get Finch helped out of his navigator's chair on the Nostromo set. Sent off to hospital, the actor was diagnosed with diabetes. Scott spent that evening talking a now-returned John Hurt into the part at his Hampstead home, and went on to work with Finch again in Kingdom Of Heaven (2005). The shot where Finch fell ill is included, with the actor's permission, on the Alien Quadrilogy extras, though I don't know if that was the only thing he filmed."
