Continuity mistake: When Arthur's neighbour walks on him drying himself up in her living room, the leftmost toy on the table in front of him has the shape next to the unicorn fitting the board in the front view, but in the reverse shot the piece is off the slot. (01:17:20)

Sammo ★

Continuity mistake: In the shot when he turns the last 2 corners in the corridor before getting to the stairs, the file in Arthur's hands is facing the opposite way compared to before and after - the label should be on the inside, not the outside. (01:13:20)

Sammo ★

Continuity mistake: Thomas Wayne and Arthur Fleck are talking in the bathroom. Joaquin Phoenix's hair changes position on his forehead several times even when he does not touch it and/or shakes his head. (01:06:15)

Sammo ★

Continuity mistake: During the scene when Arthur is making funny faces at the kid, the hair wisps on Joaquin Phoenix's forehead change position between shots. The mother also turns slightly towards him in almost every cut, but his antics are in continuity. She keeps 'just noticing' him and turning towards him without the opposite movement to balance. (00:07:45)

Sammo ★

Continuity mistake: Arthur is taking notes during the standup comedian's performance. There are a cigarette lighter and a packet next to him on the table; in the close-up that follows, they have changed position. (00:25:45)

Sammo ★

Continuity mistake: In the close-up of the gun at the beginning of the scene when Arthur is watching "Slap that bass" from "Shall we dance", notice in background the bullets; there is one angled parallel to the gun and 3 more at a slightly different inclination, plus one at right angle with the first (plus other 2 not quite aligned with the rest). A couple seconds later he aims the gun at Fred Astaire, and that group of bullets changed angle entirely. (00:22:10)

Continuity mistake: After the gig at the comedy club, Arthur and the neighbour Sophie pass in front of a newsstand. The copy of the Examiner saying "Killer Clown On The Loose" is kept in place by a clothing pin placed diagonally, top right-to-bottom left. In the close-up when Arthur looks at it, the pin is top left-to-bottom right. (00:45:25)

Continuity mistake: Arthur gets on stage at the improv club and has one of his laughing fits. When the camera is behind him, facing the blinding stage lights, you can see that he is choking himself with the right arm and holding the book with the left. But it was the exact opposite in the previous shot. (00:43:44)

Sammo ★

Continuity mistake: The last of the Wall Street Three is shot as he tries to flee; he falls down in two very different takes. In the side view he choreographically falls with the jacket rolling up his back, and with the left leg (initially) forward, foot on the ground. In the previous view, camera behind Joaquin Phoenix, he fell with the sole of that foot kicked back, and with the jacket still down his back. (00:32:25)

Sammo ★

Continuity mistake: Arthur finishes the last yuppie off, and he lies stone cold dead on the stairs. However, he is not lying in the same position the two times it is seen. The second time he has his left hand one step lower than the right (which was the only one visible earlier) and his knees are on the platform (in the first shot, only the tip of the shoes touch the floor). (00:33:45)

Sammo ★

Continuity mistake: When one of the Wall Street Three charges the punch to hit the not-yet-Joker, his buddy in the background holds Arthur's bag with the hand on top, to the point that right before the cut his thumb sinks in the bag making it bend. When the punch lands, he's holding the bag by the side. (00:32:15)

Sammo ★

Continuity mistake: Arthur tries to get up from his seat, but one of the yuppie bullies restrains him. Then the lights flicker for a moment, but it's an editing trick, as something else changed in the car; the chips' paper bag that was sitting on one of the seats in the row facing Arthur's, is suddenly gone. It comes back right after, when Arthur is struck down by the punch, and it keeps coming and going. For instance; Joker shoots the second guy dead? Bag's on the seat. Third guy runs away? Bag gone. (00:32:05)

Sammo ★

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)

Sammo ★

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)

Sammo ★

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)
