Plot hole: The "death" of the three astronauts and the requirement to then fake the whole scenario of the failed mission was obviously unplanned - it came about because of an unexpected computer glitch which reported that they had burned up on reentry, causing a mad scramble to cover up the fake mission and kill the astronauts. Obviously it was planned to have the astronauts "return" to Earth as heroes after their supposed trip to Mars, maintaining their deception (under threat if necessary) for the rest of their lives. One problem. Every scientist on earth would be champing at the bit to get their hands on a sample of Martian rock. Samples would be worth billions, worth far more than Moon rocks are worth today. How was NASA going to explain they didn't have any? They could not possibly fake the rocks - Martian soil and rocks would have a number of identifiable characteristics that a smart first year college student could identify. Using Martian meteorites collected from the Earth's surface won't work, either - prolonged exposure to the Earth's atmosphere would leave tell tale weathering and chemical changes that would be instantly detectable. NASA have painted themselves into a corner and that is not something they would have failed to realise well in advance.PEDAUNT
Continuity mistake: A shot of the chiefs' bench shows Newman on the left and Ontkean on the right. Ontkean says "I can't believe my frigging eyes." Neither can I. The next 2 rapid camera cuts show Ontkean on Newman's left, then on Newman's right again.
Other mistake: One visual that has always bothered me that I could not find in your list were the scenes when the mother ship first appears. It's enormous scale appears to dwarf Devil's Tower and the whole surrounding area actually, but when it moves over to the "landing strip" area and begins to rotate 180° (right-side up?), it suddenly seems to shrink to a much smaller size and mass during the slow revolution. On its originally-seen scale above/behind the tower, one would think that either the great ship's outer prongs would have been torn off, or more likely the impromptu landing site and most of Devil's Tower would have been destroyed as the huge craft rotated itself. The visual scales just do not stay consistent throughout the film's climactic final act.
Factual error: Most of the parachutes are PX type. These came out in the 1960s. They only used X type during the war - only a few of those are seen in the film. (00:07:00)
Factual error: After the plane is submerged, Jack Lemmon says, "... this plane is pressurized!" Jet aircraft are pressurized by bleeding air from the compressor sections of the engines into the cabin; in other words, the plane is only pressurized while the engines are running. Also, aircraft are only pressurized to a few psi above the outside air pressure at altitude, and never to more than the air pressure at sea level. The water pressure would be a great deal higher than the air pressure in the cabin, and since aircraft are not water tight, the water would quickly fill the aircraft. (If the aircraft was in 50 feet of water, the water pressure would be 21.7 psi, versus a maximum cabin pressure of 14.7 psi.)
Continuity mistake: When the crew hauls the female orca aboard the boat, the harpoon line is wrapped around her entire body several times. When they cut the rope and drop her into the water, the line is wrapped only around her tail. When the male orca is pushing her at sea, the rope is again wrapped around her entire body.wizard_of_gore
Factual error: After mounting armor in the bus they are approaching Phoenix on a two lane highway from the northwest. When entering the city they are shown coming around South Mountain on Interstate 10 from Tucson from the south.
Factual error: Just after the start of the Korean War, McArthur places a map of Korea on the hood of a jeep to explain to a subordinate general his plans to invade Inchon. The map shows the boundary of North and South Korea not along the 38th parallel, which was the border at the time (1950), but along today's DMZ - not established until the Korean armistice was signed in 1953.
Continuity mistake: When Evel Knievel goes to the insane asylum to break his buddy Will out of the institution, he crashes through the front door with the Stratocycle, breaking off the airplane-style wings on each side of the bike in the doorway. In the next shot, as he rides down the hall, the wings are still intact.
Revealing mistake: In one scene, focused only on an actress's hand holding a lit cigarette, it dawns on you that the smoke is curling back downwards and the cigarette is miraculously getting longer. This is a flipped shot, it is seen backwards.
Plot hole: "The regiment headquarters calling for Corporal Steiner. Come in Steiner." The film starts with this repeating radio message. It's even heard by Steiner and his men who are on their hush-hush job behind the enemy lines: a reconnaissance mission. Calling Steiner just makes no sense, especially with the name.S.Holmes
Continuity mistake: Philippe Noiret is sitting in his chair, drily commenting on the display previously offered by Charlotte Rampling when she was bare-breasted. During the scene, the position of his glasses as he suckles on them changes frequently, and at one point the arms go from folded 90° to less angled/straight as the view changes.Sammo
Deliberate mistake: After the chopper drags the blimp about a mile out to sea, Kabakov unhooks it, and the blimp's bomb explodes seconds after. Why would he unhook it that close to shore with the dirigible's engines still pushing it back toward land and all those people? He had no idea when the bomb would go off. The bomb's fuse was set by hand inside the gondola.
