Deliberate mistake: The song "If you give me your attention" (from "Princess Ida") and the Mikado's song (from "The Mikado," of course) are performed with their central verses omitted. This was no doubt to save time and, in the case of the Mikado's song, to avoid inclusion of the line "is blacked like a ni**er" (altered in 1948 to "is painted with vigour").

Deliberate mistake: When Venus de Milo walks toward the back of the fluorescent "ZOO" sign (presumably on the way to her death at the hoofs of the zebras), the "Z" is reversed (that is, it appears unreversed on the back of the sign). This gives the first three letters of the word "ooze," doubtless because that is what Venus will return to. (The word "ooze" is used earlier in the film in just such a context (00:34:35-00:35:50).) A tree blocks the space where the "e" would be (or rather would not). (01:41:55 - 01:44:05)

Deliberate mistake: After being stabbed, Arbogast falls down the stairs in an impossible manner. He is standing tilted backwards all the way down the stairs.
