Visible crew/equipment: In the scene where Dr. Evil tells Austin that he is his father, if you look closely at the lower left of Dr. Evil's helmet, there is the reflection of a stagehand standing by one of the windows.(There are many reflections on his helmet, so you may want to pause it so you can look around for it.)
Continuity mistake: In the "Starbucks" scene you can see a paper cup of coffee, and a muffin on the table in front of Dr. Evil. (His pocket mirror is not visible in the first shot.) During next two minutes of the film the different items continually change their positions with the different camera angles; furthermore a piece of paper appears and disappears. (00:14:05)
Continuity mistake: When Austin and Mini Me are fighting Mini Me hocks a loogie in Austin's face. The spit disappears almost immediately but we never see Austin wipe it away.
Continuity mistake: When Dr. Evil is singing "Just the Two of Us", as he says "C'est la vie" Scott walks past him, Dr. Evil looks at him (he walks to the right). Then Dr. Evil turns around about 4 seconds later and Scott is back standing by Frau and Number 2. He couldn't have moved THAT fast. (01:00:30)
Continuity mistake: When Austin has just come back from the future and has been in the party with all the shooting, he and Felicity jump in the car in the middle of the night. One second later there's a back shot inside the car and it's dawn light. Two seconds afterwards they're driving down the road and it's broad daylight. Furthermore, the light changes from sunny, to a bit cloudy in each shot.
Other mistake: When Frau shoots the gun out of Austin's hand, she fires from behind his back. She would not be able to do this unless she shot through him. She also would not be able to see his gun from behind him as he was holding it at waist level. One of those new boomerang bullets?
Factual error: When we have the last montage of jokes about the shape of Dr. Evil's rocket, it is 1969. You can tell from the clothes and the fact that Dr. Evil left in the rocket from the moon base and Austin and Felicity had to go forward in time from the moon base to get back. Now in this montage we see Woody Harrelson (in a cameo) who is apparently an accomplished actor in 1969. One small problem: Harrelson was born on July 23, 1961 and therefore would be around 8 years old.
Continuity mistake: In the scene where Felicity and Austin are dancing in the street whilst Burt Bacerack is singing, there is a couple sitting at a table behind them. The shot keeps changing between the couple and Burt and the lady's handbag keeps changing position and angle between shots.
Continuity mistake: Just at the scene where Ivana and Austin are playing chess - just afterwards when Austin asks her if he "makes her feel horny", and she stands up and confesses she was sent by Dr. Evil, but finds him so sexy, etc, in the long shot showing Austin and Ivana as she is saying that, you see Austin has both hands on table, but in the short cuts of Austin close-up, he has one arm over the chair. These shots continue for a little.
