 Opening episode for season 4, at one point Crichton yells at the  intruder to get off the ship in Klingon. Ben Browder saw the actors  in their make up and asked Richard Manning (qv), one of the  producers, for some Klingon. He told the director he would be  yelling the line in Klingon. He didnt tell Raelee Hill, so that was  her real reaction when he yelled out the line.
