Factual error: When Johnny and Lorna are in the sushi bar, Lorna says 'cheers' in Japanese to Johnny before drinking Japanese sake. (An English subtitle is displayed). Johnny, obviously not knowing what he is saying replies in Japanese, and an English subtitle is displayed saying 'may all of your daughters be born with three bottoms'. The actual translation for what he says is 'May all of your daughters be born with a small penis'. (Not that any normal person would notice)

Continuity: When Johnny interrupts the wrong funeral, and Bough saves the day with his 'loony' spiel, Bough takes Johnny's gun and helps him off the coffin. The gun disappears from Bough's hand between shots.

Other: In the chase scene, where Johnny and Bough are chasing the hearse, when Bough and Johnny are discussing where the hearse went, Johnny says "They were heading south." Then he turns the steering wheel to his right, yet when it shows a view of the truck it turns to it's left.

Continuity: When Pascal's henchmen infiltrate Buckingham Palace, and force the Queen to abdicate, if you look very closely on the abdication document it is dated the twentieth of March 2003. Yet in an earlier scene where Johnny English is photographed by the speed camera that has the date 21/03/03, obviously the abdication was filmed before the car chase, and therefore the dates get mixed up.

Revealing: At the start of the hearse chase, when we first see the bad guys pull a hand-brake turn through 90 degrees in a small London side-street, if you look on the ground you can see the skid marks from what must have been the previous take.

Continuity: The first time the film of Johnny in the mirror is shown, look at the toothpaste in the bottom right corner. First you see the Aquafresh, then it cuts to Sauvage, and when it cuts back the toothpaste tube has moved. Then it cuts away and back again, and the toothbrush has moved in front of it.

Continuity: When Natalie Imbruglia and Rowan Atkinson are trying to enter John Malkovich's "chateau", when Natalie is climbing a ladder a tattoo is visible on her lower back. Later, when Pascal Sauvage (Malkovich) is being crowned, Natalie is seen fighting a sniper on the upper-level of the church. When the sniper pushes her away, the tattoo on her lower back is gone.

Revealing: When Johnny enters Sauvage's party, after he broke into his building, a waiter gives him a glass of champagne, which he drops. When a second glass is given to him, the pre-made crack on the paw of the glass is visible, prior to Johnny breaking that glass.

Continuity: In the scene where Johnny is in Sauvage's palace and drops down to take Sauvage prisoner, when the guards appear behind him the screen changes to Sauvage, and then back to Johnny, the guards have changed positions.

Continuity: When Johnny ejects Lorna Campbell from the car, then lands in the pool, you see Bough specifically uncross his legs and reach for his sunglasses, then when Lorna lifts her head from under the water you can see Bough repeat these actions in exactly the same way.

Visible crew/equipment: When Johnny English is getting out of the truck, we see a wide shot. In the bottom of the reflection you can see what looks like a clapperboard.

Continuity: In the scene in the garage shortly before Johnny is about to "strike like a coiled viper" he talks to Bough via his wrist walkie talkie – only he talks into his RIGHT wrist while the walkie talkie is on his left.

Deliberate "mistake": When you see one of Pascal's henchmen turn off the power, he is wearing a black suit. In the reflection of the glass on the power box, you can see 'Police' written on the jacket. The filmmaker chose this suit because it was black, thinking no one would see the police logo on it.

Continuity: In the scene where Johnny has just been fired and he walks glumly away, rain suddenly starts. When we get a second shot of Lorna in the window, there is no reflection of rain.

Continuity: When Bough is telling Johnny and Pegasus about the two criminals working for Sauvage, he calls Vendetta "Klaus", and indeed, the screen in front of them shows this. However, the end credits put his name as "Carlos".

Continuity: When Johnny interrupts the funeral, he speaks to an old white woman but in the next shot, he is in front of a black woman.

Continuity: In the scene where Johnny English goes down the hole, there is a shot from within the hole of him getting in. He has only put one leg in. However, in the very next shot he is halfway through to having his entire body in the hole.

Other: When Sauvage welcomes everybody to the meeting, he says "mesdammes et messieurs". On the subtitles, "et" is incorrectly spelled "est".

Other: When Johnny and Bough swap places in the truck, the truck continues to accelerate smoothly.

Continuity: At the start of the car chase scene with the hearse and lorry, the hearse comes crashing through the garage door, and onto the road. After that follows English and Bough, and then a motorbike pulls up. It is red, but in the next shot, it is Lorna Campbell's pink bike.
