Money stuffed into theatre manager's jacket pocket during the overdose scene disappears/reappears a couple of times.
The direction of the merry-go-round changes just before young Pink is put on it.
When the young Pink finds his father's service revolver and ammunition in his mother's bedroom, the ammunition has a metal jacket (i.e., the actual "bullet" part has a brass casing over it). When he dishes them out to his friends in the railway embankment, the rounds are ordinary lead rounds without the brass casing.
When the groupie (Jenny Wright) pops open a bottle of champagne, she pours it into a glass. In the next shot, however, she is drinking it from a plastic cup.
In the "Is there Anybody Out There" sequence, when Pink is clawing at the wall, the blood on his hand (from the previous, hotel-trashing scene) switches hands repeatedly.
During "Run Like Hell", when Pink's followers set an attack dog loose on an innocent man in the alleyway, the foam protective sleeve is visible on the victim's arm.
Several obvious mirror shots during the Fascist rally scenes: the crossing-hammer armbands switching arms, left-handed handshakes, the strap worn on Pink's shoulder when walking down the hallway switching shouders, the same neo-Nazi member appearing to be standing on both ends of the row of neo-Nazis while they are chanting "waiting" during the "Waiting for the Worms" sequence.
When Pink throws the television out the window before he cuts his hand, he mouths "Take that, fuckers!", but what is heard is "Next time, fuckers!" (This is corrected in the DVD release of "The Wall".)
At the intro when Pink is in his hotel room and the camera pans down his arm, he is wearing his Mickey Mouse watch upside-down.
In the "Mother" segment, his watch can also be seen upside down when adult Pink is in his bed clutching his pillow. This may be intentional as a character quirk.
