at the possibility of Serit marrying Tony as Ann informs General Kirk. The historical information on Billy the Kid's victims alarms Ann, Ray, and the General, as it records that he killed two strangers near Lincoln, New Mexico, in April 1881—just when Tony, Doug, and Billy the Kid are brought together. Production The production used sets, stock footage, and props left over from the large number of period dramas made by the 20th Century Fox film company. Even black-and-white shots purporting to show the Titanic sinking were tinted for use in this color production. Only a few actors were costumed for a given episode, interspersed with cuts of great masses of people similarly dressed from original features. Only one set was constructed for the show, that of the Time Tunnel main control room. For the pilot episode, a large control room set was built, and a longer Time Tunnel was created using optical matte shots. After the pilot episode, location changes occurred for the production of the series; Colbert and Darren shot their scenes in another studio, on the 20th Century Fox backlot, or on location, while those who portrayed the Time Tunnel personnel filmed all their scenes on a revised and smaller Time Tunnel control room set (due to the production having to use a smaller sound stage than used during the pilot filming). Some episodes featured space aliens who wore costumes and carried props originally created for other Irwin Allen television and film productions. Prop sets were similarly reused. The prop computer, however, had an unusual degree of verisimilitude because it was an array of memory modules from the Air Force's recently decommissioned SAGE computer. Continuity errors and errors in historical fact occurred in the series. In the premiere episode, "Rendezvous with Yesterday", Captain Smith of the Titanic is called "Malcolm", when historically, his name was "Edward". The names of the secondary officers are also fictitious, though Walter Lord's best-selling nonfiction book about the event, A Night to Remember, had been released nine years earlier. Tony states that he was born in 1938. A few episodes later in "The Day the Sky Fell in", he states he was seven when Pearl Harbor was attacked on 7 December 1941, which would make the year of his birth 1934, or possibly 1933, if later than 7 December. The theme tune for The Time Tunnel was composed by John Williams (credited,
