NASA consultant Jesco von Puttkamer (Jesco von Puttkamer) played an important role. From 1976 to the filming of the film, Puttkamer, a fan of the series, has been paying close attention to the technology in the script. He provided detailed notes to the screenwriter, producer, and director, and carefully reviewed every dialogue in the script. As an important behind-the-scenes hero for the entire film, Putkamo didn’t take any money.
Filming of the film started on August 7, 1978, and the first day of filming only took 500 meters of film, and the finished script was only more than one page. In order to prevent the plot from leaking, the producer adopted strict confidentiality measures. In addition to shooting in a fully enclosed studio, the crew also numbered the script and kept a list of its holders. During the construction of the set, a young visitor stole a bridge set drawing from the studio and sold a copy of the drawing to fans for $75. Paramount immediately asked the FBI for help to take over the case in Los Angeles. The police quickly arrested the criminal, who was not only convicted, but also fined $750. Although all visitors to the set are friends of the cast and crew, media reporters, fan representatives, and famous filmmakers including Clint Eastwood , Bernard Schwartz , Robin McLaurim Williams and Mel Brooks , the crew still produces for them for safety reasons. The ID card is obtained and checked frequently. All vehicles leaving the studio must be inspected by security, even the film starring.
