Revealing mistake: In the scene with the helicopter chasing them down the street, apart from the fact that the rotors should catch on something and hurl the machine into a wall, when it finally hits the wall at the end, the pilot and crew quite clearly become about 4 crash-test dummies. This wouldn't be so bad if it weren't for the fact that they are unpainted and all sit in their seats looking straight ahead with their hands in their laps while they are driven into a wall. You'd think they could have at least posed the arms over their faces or SOMETHING!
Continuity mistake: When James has just jumped out of the plane, he has a diving rig that is somewhat different to the one he has when diving on the wreck of the Devonshire. In the water, he wears a twinset manifold air-bottle rig. While skydiving, the rig was not manifolded, and the bottles were in a different position on his back. To change between the two requires some work with a toolkit, preferably on dry land.
Visible crew/equipment: When Q is showing the new BMW to Bond, Bond takes it for a spin via the remote. As it heads back to Bond and Q, you can see a driver as it passes the helicopter. (00:30:21)
Continuity mistake: Near the beginning when Bond causes mayhem, he sticks a grenade onto a moving vehicle and dives off it. As he jumps off and attacks a bad guy his collar is up (to better hide the face of the stuntman), then when it cuts back to a proper shot of him his collar's suddenly down. (00:04:50)
Continuity mistake: There is a shot from behind a video camera, showing a wire or cable coming out of the back of the video camera, however, in all subsequent shots the wire/cable is not present. (00:00:50)
Continuity mistake: In the car park, when Bond activates the car-camera the phone screen shows the car next to Bond and the black and yellow column, but not Bond, despite him being in sight.
Continuity mistake: When Bond and Wai dive into the fountain to hide from the helicopter, clothes and pots appear/disappear randomly between shots.
Revealing mistake: The first time Bond uses the remote car, there's a bulky black object moving on the rear seat, obviously a hidden driver.
Revealing mistake: In Saigon, when Bond pops a wheelie skid marks from previous takes can be seen on the road.
Continuity mistake: At the car park, Bond disappears in all the wide shots of the car but reappears in the close-ups. This was due because the stunt driver was seated in the back seat.
Revealing mistake: During the motorbike chase in Saigon, Pierce Brosnan's stunt is noticeable in many wide shots because of his hairstyle and receding hairline. (01:18:54)
Continuity mistake: When Bond is in bed with the translator just after the title sequence, the position of the sheet of her back changes between shots. Note the gap between James' hand and the sheet. (00:21:40)
Visible crew/equipment: When Bond and Lin are being chased on the bike in Ho Chi Minh City, before they have the final encounter with the helicopter. You see a few frames of the backside scaffolding of the city street set, constructed on the back lot of Pinewood Studios. (01:23:20)
