Continuity mistake: One of the Wall Street Three begins approaching Arthur, and doing so he grabs the vertical support and spins around it. There's a cut mid-spin and his buddy in the background is standing in different positions; first he is laughing leaning against the support closer to him, then he is in the middle of the subway car holding two poles. (00:31:20)

Continuity mistake: The first time we see Randall, he hangs his clown suit next to his locker; his right hand drops, but in the next shot it starts still up. (00:15:50)

Sammo ★

Continuity mistake: Talking with his social worker Debra Kane, Arthur is moving his legs nervously as she asks him about the journal. In that shot his cigarette is almost smoked to the filter, but in the next one there's still an inch to go. (00:05:35)

Sammo ★

Continuity mistake: When Joker is beaten up at the beginning of the movie, he changes position on the ground between shots. The pieces of the sign next to him also change position; in the last shot that lingers till the movie title pops up, the part with the letters "ST GO!" is face up, it was not in the previous one. (00:03:05)

Continuity mistake: Thomas Wayne is speaking on TV. Arthur shushes his mom. In the close-up that follows, suddenly there's an extra lock of hair against his forehead. (00:38:50)

Sammo ★

Continuity mistake: When Arthur is choking Alfred Pennyworth through the bars, in the shot when he says "Let go, let go!" you can see behind his head the flowers from the magic wand, absent in the previous views. (00:54:50)

Sammo ★

Continuity mistake: During the opening credits, while the main character is clowning around with the sign the same passersby (in particular two women - one with a blue coat, the other with a plain light brown one) keep walking past him in multiple shots. (00:01:35)

Sammo ★

Continuity mistake: The camera pans towards Arthur when is reading Penny's letter to Thomas Wayne; the items on the table (newspaper, pen) are in a different position compared to the rest of the scene. (00:48:35)

Sammo ★

Continuity mistake: In the last couple of cuts preceding Arthur's gun accident in front of the kids, the nurse's hands are not where they should be at the cut; her hands are on the kid' shoulders, then ears, before the cut she raises them to dance on the spot, but they are back on his shoulders in the next shot. The baby patient himself when Arthur drops the gun suddenly has his hands up under the chin. (00:28:25)

Sammo ★

Continuity mistake: Right at the beginning of the dance in the children ward, the kid with a blue hat on Arthur's right is sitting cross-legged with the hospital robe covering his calves and feet. At the first cut, his jammies and socks become visible. (00:28:05)

Sammo ★

Continuity mistake: In a close-up, Arthur grabs with both hands the gun he dropped and kicked across the hospital floor, but in the wider shot that follows he's using only the left hand, and it's also clear that Joaquin Phoenix's body is turned in a complete different way, with his feet adjoined instead of the open legs seen before. (00:28:35)

Sammo ★

Continuity mistake: In the theater lavatory, Arthur puts the usher jacket in the sink. Part of the jacket drapes to the side of the sink, but at the cut the cloth is entirely contained in it. (01:05:00)

Sammo ★

Continuity mistake: Arthur inadvertently fires a gunshot in his living room. Right as he tumbles across the table, he knocks off the table the paper bag the gun came with, and knocks towards the edge of the table a pill bottle. In the closer angle shot when he cranks up the volume of the TV set, the bag is still on the table and the bottle is gone. The newspapers are also positioned differently. In the next shot we're back to the previous state (pills up, bag down, newspapers closer together). (00:23:10)

Sammo ★

Continuity mistake: In the first shot of the pediatric ward you can see on the left aisle a plush ladybug toy. When Arthur drops the gun, the toy suddenly between cuts is found in the arms of a patient, and then on the bed by him. (00:28:30)

Sammo ★

Continuity mistake: When Arthur Fleck gets hit by the yellow sign, the sign breaks in two different ways in the two separate shots - the first time it is evident that the bottom half of the sign splits further in the middle, while in the wider angle it stays largely intact. (00:02:50)
