  • When Arthur kills the third man in the metro passage, the body slightly changes position between shots as it lies on the stairs.
  • As the police car pulls out of the studio and makes a turn, an empty NYC Citi bikeshare rack can be seen on the right side.
  • This film takes place in 1981. The Energizer Bunny is shown in TV advertisements, but in real life, the mascot was not introduced until 1988.
  • As Arthur is standing on the cop car after the crash with the ambulance, someone in the mob is holding a bat right in front of Arthur. The shot changes and there are no bats in the air in front of him anywhere.
  • In the beginning, Arthur is seen flipping his advertising sign, but this style of use did not come about until the 2000s.
  • The idea that a late night talk show would air a video of a comic from a club just to make fun of his act in 1981 is absurd. This type of thing did not take place until the modern smart phone age. In 1981, they would have had to have permission from both the comic and the club, and the act of airing it without permission likely would spark a lawsuit. This is not necessarily a plot hole. Since the act was taped in the club it could be reasoned that Arthur had to sign the rights for the publication to the club beforehand. The club could then give permission to the station broadcasting the late night show. This may seem far fetched for the real world, but keep in mind that the movie still takes place in a fictional world, which may have some different laws.
  • Set in 1981, there is an Kellogg's ad playing with Keanu Reeves on a TV/digital billboard. This ad did not come out until 1987.
  • Set in 1981, the ambulance that strikes the police car containing the Joker is built using a Ford E-Series 1992 model or later chassis.
  • The ambulance that hits the squad car is a 4th generation Ford Econoline, that came out in 1992.
  • In one scene a BMW 3-series (E30 model) is shown parked along the street. The E30 was first introduced in the U.S. in 1984, three years after the film's 1981 setting.
  • Contemporary era toys and dolls, not introduced until well after 1981, can be seen in the Children's Hospital room.
  • Tactile paving slabs can be seen at a pedestrian crossing near the bank that Joker follows Sophie to, but this system wasn't introduced to the US until the 1990s.
  • The car that almost hit the Joker as he was chasing the teenagers was a 1989 Caprice.
  • In the ambulance scene you can hear, very faintly, the chirp associated with a trunked radio system. This kind of dispatch was not in use even in major metropolitan areas until at least the late '80s or early '90s.
  • When Arthur kills the three men in the subway, he fires eight shots without reloading his gun. Inside the car, he shoots the first man in the head, the second man twice in the chest, and the third man in the leg. After they leave the car, he shoots him once in the back, then approaches him, and shoots him three more times. A .38 revolver holds only 6 bullets. However, as it has been shown that Arthur remembers things differently than how they occurred (such as the comedy club scene), it could be possible that Arthur either remembers things differently from how they actually occurred, or that it did not happen at all and is all happening in his head.
  • In one of the scenes, Joker is running in his big clown shoes and a second later he's running in his black street shoes.
  • When Joker is dancing on the stairs he throws his cigar. Then when the cops arrive at the top of the stairs we see him blowing smoke from the same cigar. Then the cigar is gone again.
  • The sign with "everything must go" breaks a second before it hits Arthur.
  • Arthur's left eye make up changes shape (blue messy cry smear) and size before going on the show, then is very neat on the show, and then jumps back in the police car to being smaller with the left eye crying look.
  • After Arthur steals his mother's file from the clerk at the mental hospital, he races down the hallway and turns toward the stairs. You can see the stuntman's face for a split second; it's clearly not Joaquin Phoenix.
  • When Joker awakens on the hood of the police car, he's clearly laying on a fake background, as the size, shape and dents are very different than the actual hood shown in the next wider shot.
  • When Arthur gets in his refrigerator in his apartment, he pulls the door shut tight. Doing so would lock it with no way to open it from the inside, yet he appears in the next scene with no explanation of how he escaped.
  • A 1986 Chrysler LeBaron Convertible can be seen parked up.
  • When Arthur is taking a smoke break outside the hospital and the detectives confront him, he gets up and tries to re-enter the hospital, but the automatic door doesn't open. Arthur waves frantically at the motion sensor atop the door trying to get it to open. However, motion-sensing automatic doors were extremely uncommon in 1981; the older bottom mat weight sensor-based "supermarket door" style would have been prevalent for automatic doors.
  • When Arthur seems to smother his mother in the hospital, she has a nasal canula in her nose which would theoretically have the oxygen in it she would need to survive the attack. However, the tube would bend and close up, preventing the oxygen from flowing. Once she stops breathing, the flow would be inconsequential.
  • When Arthur killed his mother, the electrocardiography beep sound remained normal. Dying by suffocation would have caused a tachycardia or at least an increasing heart rate. In that case, nurses would be alarmed immediately, and Arthur may have had problems leaving the crime scene.
  • In the Children's Hospital, there is a medical cart that is color coded behind Arthur. This color coding is aligned with a Broselow Tape which is used in pediatric emergencies. The tape, which was first produced in 1985 for mass use, is placed next to a pediatric patient and the size of the patient from head to toe is in a weight based colored box. This box has written information about medication dosages and equipment sizes. The cart is colored to match this tape.
  • Kenny's music has a window full of 2018 D'Angelico guitars.
  • The blue paint under Joker's left eye changes length from when he exits the train and enters Murray's studio.
  • Being at the age of 43, Phoenix was far too old to be playing against an eight-year-old Bruce Wayne. By the time that Wayne would be old enough to be Batman, Joker would be in his seventies.
  • In the final shot, as he's leaving the doctor's office, trailing of bloody footprints, the third step of his left foot doesn't leave a mark.
  • When Arthur goes to the public theatre to confront Thomas, there is a shot of the stage with two speakers visible on either side of the stage. These speakers are modern rigged speaker arrays, which were not yet used in the 1970s.
  • In a scene in the metro hallway, the posters of 2018 movies and series can be seen. However, the movie takes place in 1981.
  • A sign in a shop window declares "Cell phones fixed here". Cell phones did not exist in 1981. The earliest cell phones were introduced in 1983 and it would be several more years before such signs became commonplace.
  • The boy whom the Joker makes faces for in the bus is missing in the long shot taken from the front of the bus.
  • Arthur shoots the 3 men on the subway, he is using a Smith and Wesson Chief Special 38 that holds 5 rounds. You can count a total of 8 shots during the scene, but he does not reload.
  • When Arthur Fleck is retrieved from the police car by two clowns at the end of the film, there is clearly no glass at all in the window that they pull him out of and they do not need to take much care in moving him. In the aftermath of a real car crash of this sort, there would still be pieces of broken glass in the window and moving Arthur Fleck out of it would without cutting him would have been very difficult.


  • In the TV show scene, just before being killed, Murray's hands change position on this desk between shots.
