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.

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.
