Factual error: When Patton orders his driver to drive to the Carthaginian battlefield he addresses him as "sergeant". He is, however, wearing corporal's chevrons. A famous stickler for discipline and ceremonial, Patton is not likely to have made a mistake like this.
Factual error: The German fighters depicted in the film are Messerchmitt Bf 109 G-6s, and every single one of them is using the Rüstsatz VI gun pod, that is, 2 extra 20mm Mg 151 cannons. The Luftwaffe only equipped their Bf 109s with the gun pods when they were going to intercept bombers. In this movie, even on the fighter vs fighter missions, they have these gun pods, which is inaccurate, because the gun pods dramatically reduced the turning performance of the Bf 109s.
Factual error: In the scene at the Bangkok docks, the ship has the name Athena but with the Greek letter Lambda instead of each capital letter A. This would make the name something like Lthenl, and is a nonsense mix of Greek and English (Roman) letters.
Factual error: Throughout the movie, scenes of the chess tournament room show the American flag incorrectly vertically hung (stars on blue upper left is proper), while the Soviet flag is correctly vertically hung. No real American vs. Soviet tournament would make that mistake.
Factual error: Dexter the capuchin is in the African mammal display. Capuchins come from South America.
Factual error: The picture of Eddie and Teddy on the road with dad, supposedly taken in 1906, shows a Ringling Bros and Barnum & Bailey circus poster. In 1906, the Ringling Brothers circus and the Barnum & Bailey circus were two separate circuses playing in different parts of the country. They did not combine the two shows until 1919. (00:27:00)
Factual error: Lauda is an Austrian. Yet when his name appears on scoreboards with his country abbreviation, it shows AUS, which is for Australia. AUT is for Austria.
Factual error: The type of surgery shown made by the machine transversely cuts the rectus abdominis muscles. Besides not being a standard surgical incision in order to "remove a foreign body" as stated, it seriously damages important muscles of the abdominal wall making any immediate active mobilization of the trunk virtually impossible, even under strong analgesia.
Factual error: When Laura Barns is counting down the final time and each number show up as a notification in the upper right hand corner, they should also show up under the Skype chat but instead, Laura's previous message remains.
Factual error: Denham is obviously shooting a sound film - he has a sound recordist with him along with the bulky and awkward recording equipment typical for the era, and they discuss the problems of recording dialogue on board. But not once do we see him filming with sound. We see the crew recording dialogue - synchronised sound, recorded on location, which is utterly impossible given the equipment they have and the circumstances under which the fim is being shot. We never see a microphone, a boom pole or a tape recorder. His camera isn't even 'blimped' - soundproofed - and it's handcranked, which makes a racket. They can't be planning on adding the sound later - why have the sound recordist and his bulky and heavy equipment there with them if they are? We see the crew recording dialogue - synchronised sound, recorded on location, which is utterly impossible given the equipment they have and the circumstances under which the fim is being shot. The whole point of post dubbing dialogue is that you don't need a sound recordist in the first place.
Factual error: While the Leonov has a centrifugal section to simulate gravity, the ship's bridge is not part of it (evidenced by the stationary views outside its portholes). Yet in various scenes, including the one when Floyd rushes in to discuss his plan to return to Earth sooner with Tanya, gravity seems quite evident. Floyd marches across the compartment onto the raised pilot area's floor, then steps down from it, his foot landing audibly. Tanya's open jacket also hangs down normally as she moves about. Yet when Floyd demonstrates his plan using two pens, they float in mid air. (01:26:50)
Factual error: A flight manifest would never state on its seating chart that an armed U.S. marshal was on board as it gives away that person's identity and puts everyone on board in danger.
Factual error: Tom Cruise says of the song 'Sitting on the Dock of the Bay' "my folks loved it". However, his father died in 1965, his mother died "shortly after him", and the song wasn't written until 1967.
Factual error: On the plane, while being escorted by FBI agents, Frank Jr sees New York's LaGuardia Airport and says, "There it is, LaGuardia Airport, runway 44." A runway numbered 44 is impossible. No runway can be numbered over 36 because there are 360 degrees in a circle. (01:58:25)
Factual error: The type of book that Eli is protecting would actually be just a fragment. The complete Bible, in braille, occupies as many as 18 volumes.
Factual error: At the end when Ben Willis and his son have Julie at the graves, Ray shows up with a gun. He fires at Ben but there is no bullet in the chamber. Later after the fight between Ray and Ben's son Julie picks up the six-shot gun and fires 8 shots at Ben.
Factual error: In the cardiac resuscitation scene with Brian Cranston, someone says "he's in atrial fibrillation... Give him 1 milligram of epinephrine." Wrong drug, in fact one that would very likely kill him immediately (maybe that's why he didn't make it!).
Factual error: That is not a crocodile that attacks Sue. It more closely resembles an American alligator - the squat, rounded snout gives it away. Australian crocodiles have a much sharper, more angular snout. There are other tell-tale physical features, most notably the placement of the alligator's teeth when it closes its mouth, but that's the main one.
Factual error: In the poster shot and in the film, the wave from the Atlantic carrying the carrier JFK into a collision with the White House comes crashing in from the west because the south portico of the White House is seen. The Atlantic Ocean is east of Washington, so the wave should come from the other direction. And even a wave coming from the east could not have made the JFK (CV-67) crash into the White House because the carrier was retired in 2005 and is berthed in Philadelphia, which is northeast of Washington DC. (01:30:10 - 01:30:40)
Factual error: The opening shot (of the New York Stock Exchange's trading floor) has the subtitle "1985," which might lead one to expect that at least the action in the first few scenes takes place in the year 1985. However, when Charlie Sheen is talking to his Nimrod broker buddy the Nimrod jokes that the day the Challenger exploded, Gekko was on the phone "selling NASA stock short." The Challenger exploded in January, 1986, not 1985. [An explanation for this: Wall Street, as conceived and filmed, was supposed to be set in 1987. However, near the end of 1986, The Ivan Boesky insider-trading scandal hit, many rules were changed, and acknowledging those events would have undone much of the plotting of the movie. So the movie was shifted back in time to 1985 (before the scandals, and also before the Challenger disaster), thus creating this major goof].
Suggested correction: You can tell by the shape of the snout and the ridges above the eyes that, although animatronic, it is meant to be a Marine Crocodile that is native to Australia. It doesn't resemble an American alligator, which doesn't possess those pronounced ridges. Also, freshwater crocodiles can be seen in the boat ride scene where Mick motions for Sue to lean up off the edge of the boat. They have the narrower, angular snout that you referenced.
The placement of the alligator's teeth when it closes its mouth shows that it is more like an alligator than a crocodile. In fact, the animatronic puppet is a bizarre mish-mash of physical characteristics of both crocodiles and alligators.
