King Abdullah II bin al-Hussein (Arabic: عبدالله الثاني بن الحسين) (born 30 January 1962; age 53) is the king of the Hashemite Kingdom of Jordan. An acknowledged fan of Star Trek, King Abdullah (then a prince) appeared as an uncredited extra in the 1996 Star Trek: Voyager episode "Investigations". Voyager executive producer Jeri Taylor commented, "Take away the title and the trappings, and at the core you have a Star Trek fan." (Star Trek Monthly issue 16)
Abdullah's cameo was arranged as a surprise for him by his US advisor. The prince – who, at the time of his cameo, was thirty-four years old – enthused, "I would have been thrilled just to visit the set but this is too much." After being put into makeup, given pointed sideburns and then fitted for his uniform (a lieutenant of the science/medical division), he rehearsed and shot his scene. (TV Guide, 17-23 Feb., p. 26) He appears in the episode's opening scene as a science officer who speaks with Harry Kim as the scene fades in. He was not given any spoken lines, however, because he is not a member of the Screen Actors Guild. After filming his cameo, he was crowded by well-wishers, including Robert Picardo, who secretly presented the delighted guest with an autographed picture of himself in his role of The Doctor. (TV Guide, 17-23 Feb., p. 26) Abdullah subsequently gave a party for the Voyager cast. (Star Trek Monthly issue 16) During his time on the Star Trek: Voyager set, Abdullah also invited Robert Picardo and Neelix actor Ethan Phillips to his own country of Jordan, an offer that Phillips took up during the hiatus between Voyager's second and third seasons. (Star Trek Monthly issue 20)
Abdullah was crowned King of Jordan in 1999. Currently he is the majority local investor of a Star Trek theme park, named Red Sea Astrarium, in the Jordan city Aqaba. The centerpiece of this theme park will be the Star Trek themed space flight adventure created under license from CBS Consumer Products. The park will open for business in 2014.
