Factual error: The camera starts out-of-focus looking down a crowded sidewalk full of background actors in period clothes and hairstyles (1973). As the camera racks into focus, Sam is walking toward the camera with many awnings visible in the background - a large blue one reads "24 Hr ATM". Though versions were invented prior to 1973, they didn't come into wide usage until the mid-to-late-80's and certainly weren't available in East Village bodegas at the time of this episode.
Revealing mistake: When Harrow and Nicholls are in what is supposed to be Queensland Police Headquarters, a window is visible with logos for Radio National and Triple J behind them. This shows that the scene was recorded at the offices of the Australian Broadcasting Corporation. (00:31:04)
Factual error: Radio talk show host David Campbell works at "WRQE 480 AM." There is no such frequency. The AM radio dial begins at 530.
Continuity mistake: When Dr Jeremy Kates rushes into the ER when Frank crashes, he doesn't have surgical gloves, a moment later you see him draining fluid from his heart and he is wearing gray gloves.
Revealing mistake: At the end it is not Helen against the filing cabinet - the face is different. Obviously a body double.
Continuity mistake: "A Stranger in Time, Part 2": Darien's arrival in 1993, shown in part 1, is recapped in part 2. But the director appears to have chosen different takes for the recap. Much of the dialogue differs substantially, and Selma's explanation that he's materialized in the ladies' room is left out altogether.
Continuity mistake: In episode 3, "How Billy Got His Groove Back", in the scene where Mick is meeting with Eduardo on the overpass Mick's sunglasses keep switching between being up on his nose to down on the tip of his nose to being off his face and back on again.
Continuity mistake: When Bug speaks with the beautiful widow the second time, about performing a noninvasive autopsy on her husband, her long hair continually changes position in the shots that face her.
Factual error: Superintendent Kane wears the insignia and uniform only worn by the Commissioner of the Metropolitan Police, not only six ranks above the rank he is supposed to be, but in an entirely different police force.
Continuity mistake: In season 4 of Prison Break, Mike Scofield's tombstone date of death shows 11-4-2005 but in this the date is 11-4-2010.
Continuity mistake: Ava spills Coke on her blouse and creates a big circular stain. As she walks to the bathroom, the stain becomes a long narrow one. When she is leaving the pizza place, the stain is still narrow, but much shorter. (00:21:00 - 00:22:00)
Factual error: There is no physical way that Steve Austin could perform most of his superhuman feats of strength in the ABC television series, due to the fact that they simply replaced his arm and legs, but didn't rebuild or reinforce the rest of his skeleton and muscles to handle the physical loads. Interestingly, author Martin Caidin (creator of Steve Austin in his novel, "Cyborg") actually did describe an incredibly complex whole-body rebuild that included vertebral reinforcement and ribcage and pelvis replacement, which was far more scientifically-accurate than the subsequent ABC television interpretation. ABC only accepted the series on the condition that it was less technical for their audience.
Log 1: The Impossible Mission - S1-E1
Character mistake: They turn left onto Moorpark St and they say into the radio they are going east on Moorpark. However, the street sign shows they are going west. (00:10:30)
Revealing mistake: At one point when Alan's phone rings (Nokia 8310) he answers it and talks to the caller yet it's obvious he isn't talking to anyone. He blatantly presses the red/cancel button to answer the call. The image hadn't been reversed though, because he pressed the exact same button to end the call.
Visible crew/equipment: In "Don't Pet the Teacher", when Jeffrey Stone talks to Albert the janitor, a boom mic briefly dips into the shot over Jeffrey's head. (00:06:10)
Visible crew/equipment: Diamond parks outside the apartment house, and when he opens the car door, it mirrors several stage lights and reflectors.
Kingdom Come - S1-E6
Other mistake: At the start of chapter 12 in the episode "Kingdom Come," Frank returns home via taxi. In front of his house in Seattle, WA, there is a blonde woman walking a Rottweiler dog. This same blonde and Rottweiler can be seen walking by the crime scene in San Francisco in the "Gehenna" episode.
Continuity mistake: When Sheila Carlisle has hanged the dead head up on the wall of Eugene's office, they are all looking at it and the eyes are looking straight in to the room. Later in the episode, the eyes are looking more to the right.
Continuity mistake: When Shirley walks through the door you can see over Alan's shoulder that he's reading the comics in the daily paper. As they talk the paper changes to the business section.
