Voyage’s pilot episode (Eleven Days to Zero) began filming in late fall of 1963 (and then aired on Sept. 14, 1964). During the filming of the pilot, President Kennedy was assassinated on Nov. 22, 1963. Production came to a complete halt (along with the entire nation) in the aftermath. They couldn’t make up the lost time, so the producer had to cut and insert parts of the movie film into the Presentation Reel for the networks to represent some of the things he intended to do with the series.
