"Underwater City" was officially filmed on August 31, 1976, at the office designed by Ken Adam in Pinewood Studios for Soviet generals. On September 15th of the same year, director Louis Gilbert began to direct the filming of Dagangya "Richard Chire". The stunt director Bob Simmons even performed the stunt of head hitting the real glass and flying out of the train car instead of Richard Chir. At the same time, Ernie Day, the director of the second film crew, was shooting a new handmade Lotus sports car in the film in Sardinia, Italy. In order to find a second identical Lotus sports car, the crew even borrowed a special car from Chapman, then chairman of the Lotus Corporation. In addition to completing the sports car scene, the second film crew also filmed the tanker model and the underwater city model in Panama. On the other side of the Atlantic, the first film crew went to Egypt and invited excellent visual effects designers from Hollywood to cooperate with the shooting. But the terrible food in Egypt made the entire crew suffer. The only producer, Kobe, personally cooks pasta for the staff in order to boost morale. Of course, the ingredients have to be airlifted from Cairo to the filming location. Despite the challenges, the filming continued. Ken Adam completed the construction of another huge sceneon the Pine Forest after "Thunder Valley" . Because the set was too large, Ken Adam also lost his confidence in the past, so he invited director Kubrick to see what else the set needed to be improved and perfected. Kubrick provided Ken Adam with advice very low-key. This huge set was officially opened on December 5, 1976, and the opening ceremony was presided over by the former British Prime Minister Sir Wilson
