Continuity mistake: When Austin is unfrozen you see the two nurses remove the wires clipped to his ears, then suddenly they are back. (00:11:35)
Continuity mistake: When Austin and Vanessa are on top of the bus, for one shot Austin's teeth are clean.
Continuity mistake: When Austin and Mrs. Kensington are at the Swinger's Club and the waitress gets punched in the face her hat falls off. In the next shot he/she is still wearing it. (00:05:10)
Continuity mistake: After Austin and Vanessa's night on the town, she falls asleep on Austin, holding a champagne glass. When the laptop computer starts beeping, the camera angle changes as we see Austin push her off him, and the champagne glass has suddenly disappeared. (00:41:15)
Continuity mistake: In the scene near the beginning when Austin is walking around naked and Vanessa is holding a magnifying glass she is concentrating very hard on watching the monitor off the screen. (00:35:30)
Continuity mistake: In the scene where Austin gets stuck in the golf cart between the walls the number of poles in the bottom left corner keeps changing and they get further and nearer apart.
Continuity mistake: In the scene where Austin is about to get in the jacuzzi with Alotta Fagina his hair is messed up from taking off his shirt, but when it shows him getting in it's fixed. (00:44:40)
Continuity mistake: In the one scene in Dr. Evil's evil headquarters, it shows the large screen opening in front of them. The screen shows the warhead that they're going to arm the drill with. The table in the room is reflective, it shows the panels of the screen opening, but it does not show the image that's on the screen reflected in the table.
Continuity mistake: In the scene where Vanessa gets drunk and the laptop rings, the first time it shows the laptop, there is an alarm clock behind it. First it reads about 10:30 or so. The 2nd time it is off. (00:41:25)
Continuity mistake: Towards the end of the movie Dr. Evil is talking to Austin in his evil headquarters. Dr. Evil is sitting in a chair with Mr. Biggelsworth in his arms. The scene has close ups of Dr. Evil with a sleeping cat, and broad shots of Austin and Dr. Evil, with the cat trying to get away. It keeps switching from one shot to the other.
Continuity mistake: In the scene with the American General talking about the Big Boy and asking a person to call the president, pack my overnight bag, etc., you can see his face blur over and jump from spot to spot. (00:07:15)
Continuity mistake: When Austin is working his mojo on the fembots, take note of his pile of clothes that have been carelessly tossed into the corner of the room. Whenever the shot returns to Austin dancing around, the pile of clothes seem to have changed their arrangement. (01:14:00)
Continuity mistake: When the security guard comes back with the orange sherbet, he hands it to Austin who takes it from him. But a few seconds later, when Austin and Vanessa are escaping from the destructing lair, neither Austin or Vanessa have the sherbet with them. [Just a note regarding this scene, the international version of the film contains this scene but not the US version. I believe it is a deleted scene on the US version of the DVD.]
Continuity mistake: When Austin gets unfrozen and is taking a shower, when he finishes he still has some of the "warm liquid goo" running down the left side of his face (his left). However, when he's about to get dried off, the goo isn't there any more. (00:09:35)
Continuity mistake: When Austin first encounters the fembots, just right before the lead one gasses him, and the nozzles come out, look closely at the bottom left of the screen (during the headshot of the lead one) and you'll see the nozzle is already out on her left breast.
Continuity mistake: This mistake takes place when Austin, Vanessa, and the guard are with the mutated sea bass. When Austin judo chops the tooth paste onto the guards face, the guard is wearing a helmet and half of it has toothpaste on the front. Then the camera does a close up on Austin. When it shows the guard again, he doesn't have his helmet on and half of his forehead has toothpaste instead of his helmet.
Continuity mistake: In the scene in the toilet, we clearly see that his pants are pulled down in one shot, but then when he's drowning the Irish guy, they are suddenly pulled up again. (00:31:55)
Continuity mistake: Watch the distance between Austin and Basil Exposition just as their first meeting comes to a close. It changes from far to near and back to far in the space of a couple of shots!
