Continuity mistake: When Austin is driving with Foxxy and Nigel he is wearing a pink and black striped suit. When they almost hit the bus the stunt driver is wearing a dark blue suit.
Factual error: When Austin is showing Foxy the internet, the URLs on the bottom of the page refer to domains that end in .UK.GOV. All UK Government web sites end in .GOV.UK. The .GOV suffix is only used for US Government sites, and none of those have the prefix ".uk".
Continuity mistake: Whenever Goldmember undresses. it causes a gold glow to light up the surrounding area. Later on in the movie when he reveals the 'second key', it stops producing this effect.
Suggested correction: We still see the glow as he's getting the key.
I believe he's referring to the fact that once removed, the key is no longer glowing, even though the film indicated it glowed.
Continuity mistake: When Austin and Foxxy are in Goldmember's factory you can see henchmen working on the car behind Austin and Foxxy. In another shot the henchmen are gone, in the next shot they're back. This happens a few times.
Continuity mistake: During the fight scene between Austin and Mini Me, Austin knocks over a lamp and it lands directly in front of the coffee table. A couple of shots later it is now off to the side of the table.
Continuity mistake: In the scene where the Frau visits Dr. Evil in prison, the guards' position in the background changes from shot to shot - arms crossed, on the side, hands folded...
Visible crew/equipment: In the shot where Austin is on the bed with the twins, the one on Austin's left lifts up her ankle on the bed. There is a cable visibly stuck on her shoe. It slips off after about a second.
Continuity mistake: The rearview mirror of the BMW Mini is visible during the exterior shots of the car. However, in all the interior shots it's gone.
Continuity mistake: In the scene that Austin is talking to Fat Bastard just after he jumps trough the bathtub, there are two fat guys behind him, in the next shot, one of them is in a different place.
Other mistake: In the middle of the movie after Goldmember brings out Austin's father, he knocks out the guards. Two shots later for about three seconds you see the guards getting up.
Continuity mistake: When Austin and Foxxy are in the Shaguar lookin at photos of Mr. Robato, there is one pic of Robato and Goldmember inside the factory. That picture is a frame from when you actually see the two in the factory loading Preparation H and Goldmember receiving the key.
Deliberate mistake: Basil tells Austin he is being sent to Studio 69 located on Eighth Avenue and 69th Street in New York City. However there is no such address. Eighth Avenue ends at 59th Street, after that it becomes Columbus Avenue.
Continuity mistake: During Goldmember's entrance scene, one can see a black female skater behind him on his right and a white female skater behind him on his left. When they all get to the bottom of the ramp, the two skaters have switched places.
Plot hole: How can Austin's Father be so young? Don't forget that Austin was frozen for 30 years, so their age gap should be 30 more than normal; but despite that the age gap between them seems about normal for a father and son.
Suggested correction: This used to drive me nuts as well, until my latest viewing when I realised Goldmember first kidnaps him in 1975, and brings him to the future. As for Nigel missing Austin's award, maybe in the first timeline Nigel lives to be 95 ish.
Continuity mistake: The plate of asparagus in the fountain room is not seen when Austin first enters the room. When Austin plugs the fountain back in, the plate disappears.
Continuity mistake: When Austin and Foxy are in the time machine leaving the club about to travel to 2002, Foxy is wearing large gold hoop earrings, but after the first shot she only has one earring in (the left ear).
Other mistake: Right as Austin performs "Daddy Wasn't There", the camera moves in on the band and people move out of its way. One of the extras on the left side quickly looks right at the camera and realises she needs to move.
Continuity mistake: When Austin kicks Mini Me, the knife and envelope are dropped under him. Two shots later, the knife is still there but the envelope has vanished.
Continuity mistake: During the beginning credits with Tom Cruise as Austin Powers, he parachutes into his car. The sky during this sequence goes from a few clouds (mostly just blue sky) to overcast, and back to blue sky and a few clouds.
Continuity mistake: When Austin, Foxxy, and Mini-Me come out of the chamber from outside the sub, the water spilling out goes into a drainage grate below the door. However, the amount of water on the floor increases without very much coming out from the door.
