Austin Powers: International Man of Mystery (1997)

Revealing mistake: When they go to defrost Austin, Mike Myers is shaking inside of the huge ice cube, because he's really just doing his best to stand still. (00:08:30)

Revealing mistake: When Austin enters the bathroom at the casino, keep your eyes on the door during the scene - it opens by itself before closing. (00:31:10)

Revealing mistake: When Patty O'Brien (the Irish assassin) fails to strangle Austin in the restroom, Austin grabs him and shoves his head in the toilet. If you look closely, right before O'Brien's head enters the toilet, the back of his hair is already wet. (00:32:30)

Revealing mistake: In the scene at Alotta Fagina's penthouse, you can see the side of her swimming costume as she gets in the jacuzzi - she's meant to be naked. (Fullscreen only). (00:44:00)

Revealing mistake: When Austin lowers himself in the jacuzzi you can see he's not naked but wearing flesh coloured swimming pants. (00:44:40)

Revealing mistake: During the honeymoon sequence at the end of the film, if you look at the right top of the flowers in the vase during the "flowers covering nipples" bit, you can see a bit of red duct tape covering Liz Hurley's nipple from behind the flowers. (01:22:20)

Revealing mistake: In the scene where Austin and his allies burst through the big blue door, right before "Secret Agent Man" begins playing, the door explodes, and you can clearly see that it's made out of wood, even though it's painted to look like and is meant to be metal. This mistake is even mentioned in the director's commentary on the Austin Powers DVD.

Revealing mistake: During the Honeymoon scene when Austin and Vanessa are both naked, Austin sits down on the couch - I think it's the computer that covers him up. But if you look closely, you can see the G-string he's wearing. It's flesh coloured and hard to see, but it's there.

Revealing mistake: There are close-ups of Burt Bacharach playing piano and singing to Austin and Vanessa on top of a "bus" as they cruise through Las Vegas. From a long shot as the vehicle travels by, it's very obvious that it's not Burt playing, but a stand-in.

Revealing mistake: Watch the people who fall back into the fire, courtesy of Dr. Evil. As they fall back, watch their feet - they roll off to either the left or the right.

Revealing mistake: When Austin encounters the fem-bots, the main one begins to gas him. Then camera pans to her back, revealing the hoses emitting the gas.
