It's less than a day between the boat chase and the party in Austria. Bond suffers three large cuts on his forehead from the boat chase. In Austria, there are no signs of the cuts.
In the opening chase, Bond's car door is torn off, but as it spins around not only is the door there, but there isn't a scratch on the driver's side.
At the end of Casino Royale (2006), Bond was wearing a light-blue shirt and a three-piece suit when he shot Mr. White in the leg. At the beginning of Quantum of Solace, his shirt is white and his waistcoat has disappeared, and in fact both he and White seems to be in slightly different suits. If the events of Quantum of Solace occur an hour after those of Casino Royale, it would mean that both had an inexplicable clothing change just before the car chase. (In fact, this continuity error betrays the fact that the films' costumiers are different: Brioni provided suits before, but for this film it is Tom Ford.)
Dominic Greene boards a Bombardier Challenger 600 business jet in Haiti to fly to Bregenz. The plane one sees pulling up the ramp in Austria is a Learjet 45 or 55.
During the boat chase scene, both Bond's and Camille's hair alternates between wet and dry several times.
During the aircraft "chase" scene the left engine of the C47/DC3 is shot out. Bond then sets both engines to full power and pulls back on the yoke to initiate a climb. Being that the left engine is the "Critical Engine" for the C47/DC3 Bond's course of action would not have resulted in a climb, but instead resulted in the C47/DC3 performing a roll to the left onto it's back and most likely crashing.
Critical Engine Definition per the FAA: The engine whose failure would most adversely affect the airplane's performance or handling qualities is the critical engine. On any airplane with both engines rotating clockwise the left engine is critical. Aerodynamically, this is due to asymmetrical thrust or "P" factor. The center of thrust is offset to the right side of the propeller hub, creating a greater distance (ARM) from the longitudinal axis to the thrust line of the right engine. This longer arm in turn creates a greater yawing moment, and with rudder deflection fixed at its maximum value, airplane speed must be higher to overcome the effects of "P" factor. Failure of the left engine, therefore, creates the more "critical" situation (need for higher Vmc)
Bond arrives at the opera and steals a 'goody bag' which contains the Quantum earpiece, he tips the bag into a sink in the men's restroom to examine the contents. The sink appears to have a tap (faucet) which operates automatically when hands are placed beneath yet the water does not flow when Bond is searching through the stuff in the sink.
While in Austria you see two license plates with 4 letters before the state emblem. In reality, all Austrian license plates have a maximum of 2 Letters before the state emblem. The emblem shown was the correct one for the state that Bregenz is in, but that letter combination wouldn't be possible.
When Bond returns to his hotel to find M and other agents in his room, where they have found Agent Field's body, M tells Bond that Field's lungs were full of oil, implying she was drowned in oil. They could not have known that without an autopsy, yet the body is on the bed, untouched. So, at best, this is simply an assumption by M.
After the fight scene in the lift,'M' speaks to Bond about him being an MI6 agent. Those who work for MI5 & MI6 are Intelligence Officers. Agents are those who are recruited to infiltrate suspect groups.
Bond uses a Walther PPK pistol throughout the movie. If Quantum of Solace is set immediately after Casino Royale (2006), Bond would still be using a Beretta, as Q Branch is yet to have assigned Bond the Walther PPK. However, there is no reason an MI6 armorer could not have switched Bond from his previous Walther P99 to the PPK before he shoots Mr White at the end of Casino Royale. We do not see his sidearm, only the H&K UMP he uses to kneecap White (which he still has in Quantum). He could have had said PPK on him the whole time.
M tells Bond that a DNA analysis has been done on a lock of hair. Strictly speaking, locks of hair are cut off and do not contain the hair follicle which is preferable for DNA analysis. However, it is possible to get DNA from hair samples that lack roots, although it takes more time and effort. It is likely that the case was given priority to facilitate the effort.
It would be highly unlikely that in any country René Mathis could be charged, tried, acquitted and compensated in the time between the two films. However, there is no indication of how much time has elapsed between Bond getting Vesper's text message with Mr. White's phone number and Bond finally tracking him down. Also, Mathis was taken into MI6 custody for interrogation, not for trial.
Though the film is seen to follow on almost immediately after the events of Casino Royale (2006) and yet things such as M's office at MI6 HQ are completely different, it is clear than the final scenes of the previous film take place some considerable time after Bond finds Vesper's clue to lead him to Mr White. M has come to Italy and the sting has been set up, with a new Aston Martin and the safehouse in Siena, and White's extreme rendition arranged.
An extra in the background of the Port-au-Prince scene is meant to be sweeping the ground, but his broom is not on the floor; he is merely miming sweeping motions.
The siren of the Carabinieri's car in Siena is wrong. Sirens of Carabinieri and Police cars in Italy make a different sound than American police car.
Near the end of the movie, General Medrano opens a metal suitcase that's supposed to be full of money. However, the prop money has slid, revealing that it's only an inch deep.
During the airplane chase scene, Camille takes off her headset and runs to the rear of the plane. She yells instructions to Bond who is still wearing his headset and he reacts even though there would be no way he'd be able to hear her.
When M dresses Bond down for getting Agent Fields killed, she tells him Fields' lungs are full of oil. Fields' body clearly hasn't been moved or examined (the smooth, unbroken coating of oil on and around her body makes that obvious), so M would have no way of knowing that.
When Beam reveals Bond's identity on the jet, the actor's mustache is beginning to fall off on the right side of his lip. When we see him again, the mustache has been re - attached.
The parachute used by Bond and Camille opens far too and when they are falling too fast to be of any use to them. One or both would have been severely, or even killed, considering that they both hit the ground and not the nearby pool of water.
A cut/deleted scene from this film has James Bond killing Mr. White. However, White returned alive in the film 'Spectre', it is because the same was deleted from the finished cut and is not canonical to the story.
When Tanner searches for which Dominic Greene Bond stated, the computer read out searches "Scanning KGB databases." The KGB dissolved long ago in 1991 and was succeeded by the Foreign Intelligence Service (SVR) and what would later become the Federal Security Service (FSB)
It is clear that the outset of Bolivia was filmed in several different countries. Whereas in La Paz people speak with what appears to be a Mexican accent, people in the desert such as the desert hotel waitress and the plane owner speak with a Chilean accent. The Bolivian scenes were filmed in the Atacama Desert in Chile, Colon in Panama and the Baja California Peninsula in Mexico.
James Bond gets told on the phone that Greene's biz-jet is on a private charter to Bregenz, Austria, where he seems to land. However, Bregenz itself has no airport. Only St. Gallen-Altenrhein and Friedrichshafen are nearby (10 and 30 km, respectively). London Farnborough Airport was used for this scene.
During the opening car chase it is clear that this is filmed on the northern part of Lake Garda through the mountain passes and tunnels. After the quarry scene Bond is now suddenly driving into Sienna which happens to be around 150 miles from Verona, Lake Garda's main City location.
James Bond is clearly not in Port-Au-Prince. The harbor is all wrong, there are no luxury hotels or home on the bay and the general conditions of the building are much better than in Haiti's capital. This was actually Colon, Panama, on the Atlantic coast.
When Bond is in the airport in Austria and has his card refused the close-up of the card terminal correctly shows German messages on-screen. However the keyboard is clearly a UK terminal version.
Bond gets Elvis' mobile number and the company name Greene Planet by tricking him with a Universal Exports business card - the company's logo comes up on Bond's phone when Elvis tries the number. When Bond namechecks Dominic Green with MI6 not long after, however, having got this name from Camille, the name 'Greene Planet' seems to mean nothing to him, and he does not confirm Greene's identity until he receives an image.
The intense heat alone generated by the huge magnitude of the hotel inferno that Bond and Camille are trapped in towards the end of the film would have roasted them alive long before they managed to escape.
We learn from M that Dominic Greene was found dead in the desert with two bullets in his skull and motor oil in his stomach. Presumably Greene drank the oil, and was then shot. Why would Green's murderers kill him if he had just did that to himself by ingesting oil? If Quantum was trying to make a lesson out of Greene, why not let him writhe in agony rather than deliver a coup de grace?
Bond goes through a lot of trouble rescuing Camille in Port-au-Prince, only to give her body away to strangers as soon as they get ashore, despite her having the valuable information he needs.
Bond reads the registration of the private plane in Haiti to MI6 as G-0(ZERO)***. Its a British registered plane and would read G-O(letter).
The fire notice on the inside of the door in the hotel in Port-au-Prince, Haiti, says "En case d'incindie". The correct French is "En cas d'incendie".
The audience for the Bregenz opera is dressed formally, with the major cast in tuxedos. In reality, patrons who attend the Bregenz opera are dressed casually.
General Medrano is from Bolivia, yet he speaks Spanish with a Mexican accent.
