Goofs

When James Bond and Honey Ryder are washing themselves by the waterfall after Bond killed the guard, their clothes dry completely when exiting the water.

Annabelle breaks a flash bulb and gouges Quarrel's right cheek producing a large amount of blood. In subsequent shots there is no wound on his face.

One of Bond's traps in his room is his briefcase; he puts talcum powder on it. When he is done he sets the case down on the right side of the table. To the left is a mirror and by the mirror is an assortment of perfume bottles and a shaving bag. When he returns, the contents on the table are reversed exactly, and the perfume bottles are replaced by a magazine.

James and Honey wash themselves in the river after avoiding the dogs. Honey has taken off her swimsuit top and is wearing only her white shirt. As they run to the bank, she is not carrying her bra/bikini top, but later, when both their shirts are dry, she has her bra/bikini top on under the white shirt.

In the river, the breathing tubes are supposedly cut from the very thin reeds growing on the bank. After they're cut, they're much thicker bamboo stalks.

Tarantula bites, while painful, are hardly lethal. It makes no sense to use one as an assassination attempt.

The speedometer of the '57 Chevy shown in the chase actually is that of a '57 Ford. Also, the closeup shows a black steering wheel and dashboard, whereas the Chevy has a red steering wheel and dashboard.

When Bond has the conversation with Felix in the bar, Annabelle smashes a flashbulb and scratches Quarrel's face with it. Flashbulbs of that era were filled with oxygen to provide a good flash. Unfortunately they often exploded, so they were covered with a thick plastic coating to prevent this. If the bulb was smashed, the plastic coating, which is clearly seen as burned and blistered when she smashes it, would have kept the sharp edges safely inside, and Quarrel would not have been harmed.

The Bren gun seen on the patrol boat has no magazine attached when it is first shown. Later, when supposedly firing, the magazine, which fits on the top of the gun, is being held in place by hand... and backwards.

While looking at a photo with Superintendent Duff, Bond claims that Quarrel was the man driving the car that followed him from the airport. The two speeding cars were never closer than 30 or 40 yards from each other. Bond could not possibly have made out who was inside, in the shadows, through two windshields.

When Quarrel and Bond are getting ready to confront the "dragon", Bond tells Quarrel to go for the driver and Bond will go for the lights and tires. Earlier, they see "dragon tracks" which are from a tracked vehicle, not one with tires.

Regardless of what made the "dragon tracks" earlier, the tank that Bond and Quarrel are shooting at clearly has tires.

When Bond is sliding down the pipe, a gush of water sweeps over him. However, when he later emerges from the pipe, he is in a hallway with no trace of the water.

However, in the last few seconds of this sequence, he is clearly climbing a diagonal shaft toward the ventilation grille. Though it is odd for air ventilation for an underground facility to share a shaft with some kind of waste-water disposal system, the water would not likely have come out of the ventilation shaft.

Dr. No offers Bond a martini, shaken not stirred. Bond asks if it is vodka and No replies that it is. However, any knowledgeable drinker and bartender would know it makes no difference whether a vodka martini is shaken or stirred. Only with gin martinis does it matter, as shaking it lessens the alcoholic effect.

Perhaps Dr. No is less knowledgeable about mixology than Bond, and Bond is subtly mocking him by asking if the martini is vodka.

Honey tells Bond she has never attended school but educated herself from an encyclopedia. She also appears rather naive, saying she believes in dragons. However, she reveals that her father was a respected marine biologist and expert diver. It is unbelievable that such a qualified man would fail to provide a decent education for his daughter.

Just because Honey's father was educated in a very specific field does not mean that he had the means or motivation to provide his daughter with a quality education, he could very well have felt that a girl was not worth educating.

Bond sets traps in his hotel room, including the closet, but is wearing a darker suit when he is seen checking them later.

He changed suits in his room and reset the traps afterward; this was done off-screen as it wasn't interesting.

During Bond's shootout with the "Dragon" on the beach, he uses three different model handguns. His Walther PPK (which is Walther PP in reality) changes to a Colt 1911 Government Model, then to a Browning Hi-Power, and then back to a Walther PPK. It was reportedly caused by malfunctioning of Walther PP shooting blanks. His gun also goes into slidelock (indicating empty) twice while shooting, and without visibly reloading, continues to fire.

A protective pane of glass is visible between Bond and the tarantula. Bond can be seen squishing his arm up against it. Later, he moves his shoulder and the spider stays in place.

During the car chase with the hearse on the way to Miss Taro's house, Bond's wild movements of the steering wheel bear no resemblance to the trajectory of his car as shown in the filmed background.

M tells Bond it is 3 am when he comes into the office, yet outside through the windows it appears to be the late evening hours or sunrise.

The scene at Ms. Taro's apartment happens in the dead of night, yet daylight can be seen coming in through the shutters.

When the patrol boat is firing at Bond and Honey, the bullets have ricochet sounds even though they are firing into sand.

When Dr. No's men pass by in a boat and shoot at the shore where Bond, Honey and Quarrell are hiding, their commander shouts "We'll be back - we'll be back with the dogs!" into a megaphone, which has an echo effect. He then lowers the megaphone and waves his arm as he shouts "Full Speed Ahead!" - which has the same megaphone/echo effect, despite the lack of megaphone use.

The car chase toward Miss Taro's house takes place on a gravel road, but can the tires are heard screeching when the car goes around the curves.

When a bunch of birds suddenly take off in the jungle, the sound effects are of monkeys screaming, instead of birds chattering or wings flapping.

When Honey Ryder is introduced and emerges from the water singing, there is one shot in which her lips aren't moving as she sings.

Stunt double's face seen right before Bond jumps down into the tunnel where the steaming water rushes through.

When Honey tells Bond that the one shell alone is worth $50 in Miami, she tries to shield them from him. A piece of equipment is seen bobbing at the bottom of the screen. The full shots of them reveal no such piece of equipment.

When the hearse with the Three Blind Mice speeds away at the beginning of the film, two (Klieg?) lights are visible in the reflection on the window, as well as the outline of a crew member.

In M's office, a boom light reflects off a painting above the mantelpiece.

The camera's shadow is visible on the ground as the car goes off the cliff in the car chase when Bond is headed to Miss Taro's house.

Quarrel indicates that he visited many nearby keys with Strangways, taking various ore samples. Jamaica is essentially a single large island. Except for a few tiny near-shore islands in bays and coves, there are no out-islands near Jamaica and certainly no large private islands such as Crab Key. The suggested geography is more like that of the Bahamas, two to three hundred miles north with Cuba standing in between.

James and Honey are given drugged coffee as soon as they enter Dr. No's lair. No reason is apparent, or subsequently given, for this, and neither of them questions the reason why. In fact, soon after they wake, they are accepting food and drink again from Dr. No with few apparent concerns.

It makes no sense for SPECTRE to go to all of the trouble to sabotage the American space program in the way depicted. They have at least one relatively large nuclear reactor and major engineering capabilities. That means they can simply make atom bombs and achieve any goals by nuclear blackmail.

The shadow of a boom mic is visible on the hotel room wall behind Bond, just after the room service attendant hands him his martini.

When Bond returns to his hotel room and decides to pour himself a drink, he rejects the opened bottle of Vodka as it may have been tampered with and opens a new bottle to pour his drink. But he is happy to put ice cubes in his glass which could also have been tampered with.

The Beretta pistol that Bond has at the briefing is a model 1934 and was never chambered for .25ACP as mentioned. It was only chambered in .380ACP (9mm short) which is more powerful than 7.62mm (.32ACP) that Boothroyd states the Walther (also available in .380ACP) is chambered for. When Q branch gives Bond his Walther PPK, it's really a Walther PP.

M says Bond's PPK can be fitted with a silencer, despite the PPK not having a threaded barrel.

The space flight repeatedly is referred to as a "moonshot", but the flight is also referred to as a Mercury flight. The Mercury program was NASA's first step into manned spaceflight - single-seat spacecraft focused on low earth orbits.

During the rocket countdown, the commentary from Cape Canaveral says that this is the launch of the MA-7 (Mercury-Atlas 7) mission. This was Scott Carpenter's flight as part of Project Mercury. Just a little later the rocket is reported as being at its full weight of 240, yet the launch weight of the Atlas rocket was only just over 100 tons.
