Visible crew/equipment: After Violet has chewed the gum and is blowing up, if you look near the bottom of her right leg, you can see the air hose that is blowing her up. Visible on full screen only.

Visible crew/equipment: When Charlie and Grandpa Joe drink the fizzy lifting drink and are floating in the air you can see the hook that is connected to the wire that Charlie is being held up by.

Visible crew/equipment: You can clearly see the string holding the elevator as it flies over the city.

Continuity: Near the end of the movie where Charlie gives the gobstopper back, Gene Wilder's hair is all screwed up, but the next second it's fine.

Visible crew/equipment: In the scene where Charlie and his grandfather are floating from the fizzy lifting drinks, you can see the black harness Charlie is wearing.

Revealing: When Violet turns into the blueberry you can see the reflection of the blue light in her hair. But in the same scenes where blue make-up is used instead of the light, you can see the regular flesh-tone under her hair and in her parting.

Revealing: In the scene where Willy Wonka and the group of golden ticket holders enter the room with the chocolate river, Willy Wonka picks up a mushroom head with his cane. If you look closely, you can see holes under the mushroom head where he has previously done this, probably more than one take for that scene.

Continuity: When Mr. Wonka is first walking toward the crowd, his walk is much longer than the actual path. Watch the shadows change on the overhead shots as the day of filming went by.

Continuity: If you look closely at several scenes, Veruca Salt's and Violet Beauregard's hairstyles change. For example, Violet's hair is wavy, then it is even curlier.

Revealing: At the beginning, in the candy factory, Bill (the store owner) is handing out candy left and right and singing to the kids. There is a shot where he turns around and a girl is pretending to throw candy into her mouth. Clearly her hand is empty.

Visible crew/equipment: In the scene where the group enters the weird elevator with the escher wallpapered walls when the shot looks from the back of the elevator you can see the shadow of the camera/light reflector on Mr. Salt.

Audio problem: When Charlie and Grandpa Joe are first being lifted into the air after drinking the fizzy-lifting drinks; Charlie tells his Grandpa that it's ok. But instead of saying "Grandpa", he very clearly says "Grandma".

Continuity: When Veruca tells her dad that she wants a golden goose the stuff in the bowls behind them keeps changing.

Revealing: Just before Charlie opens his winning Wonka bar, we see printed on the back label: Packed by The Quaker Oats Company Chicago, Illinois. It is made clear in the film that no other companies are involved in the creation of Wonka's products - they're dispatched from his factory wrapped and ready to sell.

Audio problem: In the "Candyman" song near the beginning of the movie, the candy store owner is on a ladder, about to drop candy into the kids' hands. When we see the kids holding up their hands and saying, "Me. Me.", none of their mouths are actually saying anything.

Visible crew/equipment: When Wonka transports the giant chocolate bar, the stand the chocolate lies on inside the TV is visible.

Audio problem: During Veruca's song her lips don't match what she's saying.

Revealing: Right before Augustus goes up the pipe, there is a long shot of the pipe. Look very closely. You will see that there is a dummy of Augustus, not the real Augustus.

Continuity: In the scene where Wonka shows the tour the Everlasting Gobstopper machine, you can see that the candy is already on the finished belt before he turns it on. In the close up of the candy, there are a lot of extra candy, but after they get passed out, the excess is gone.

Continuity: When Grandpa Joe, Charlie, and Willy Wonka get into the Wonkavator for the first time from Wonka's office, the Wonkavator has a plain hexagonal shape. As it flies over the city, however, it sports an elaborate design complete with an ornate minaret on top.
