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)
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!
Revealing mistake: When Bond holds Carver against the computer so the big drill will kill him, you can easily see that the computer behind them isn't real. As the drill rips into the 'computer' it's all white inside, just like styrofoam. They probably used it as it gets destroyed easily and would make the drill look really powerful as bits of it flew everywhere.
Revealing mistake: When Bond drives the BMW at himself and Q in the hangar, it cuts to an interior view of the car. This scene has obviously been sped up to give the impression that the car is going faster than it actually is, evident by the vehicle's speedometer.
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.
Revealing mistake: After Bond's BMW runs across the spikes that deflate the tyres, there follows a side shot of one of the rear tyres re-inflating. If you look carefully, under the car near the wheel is the mechanism they used to raise the car to 're-inflate' the tyre.
Answer: It's getting dark by this point - Bond and Wai Lin are dressed in black in a dark coloured boat. Anyone looking out of the window would be looking down towards them - they wouldn't be able to pick them out against the sea.
