Episode #1.1 - S1-E1
Other mistake: Weol-ju goes into the forest at night and sees her house has been set on fire. From where she is standing, there is a large distance between her and the house, and the fire is so huge, that she can see it all the way from the forest. She then runs back, and given the distance between the forest and the house, should have taken a while, but the house is still in the middle of burning down when she arrives. The fire should've definitely worsened during her run back to the house. (00:12:23)
Episode #1.1 - S1-E1
Other mistake: At the beach, the detective is worried about the tide coming in, yet the subsequent tent to protect the scene is 20 feet beyond the high tide debris line.
Other mistake: Jesus leaves his home with a double barrel break-action shotgun and an ammunition belt holding extra shot-shells. In the next scene Jesus is walking in the street with the shotgun and no ammunition belt, it magically vanished. The shotgun only has a capacity for 2 shot-shells, then it needs to be reloaded, or it can be reloaded after one is only fired, that procedure is called a top-off. He fires 1 round at the mayor and two inside Elena's home which makes three. He never reloads. (00:32:50 - 00:34:40)
Other mistake: When we see the close-up of the newspaper headline that says "Ray Parents Slain" at the start of the episode, look at the smaller articles on the close-up side of the screen—they're literally gibberish.
The Hong Kong Kowloon Treasure Murder Case File 1 - S1-E1
Other mistake: Throughout the episode, certain street signs ("Job&Piece", "Ocean Guest House") are used multiple times in different points of Hong Kong (for instance the establishing shot of the city, behind Kindaichi and his friends when they meet, during the bike chase).
Other mistake: Danny Stevens, an undercover police officer, is killed. The police agree to investigate the murder of his undercover persona, Steve Daniels, thus allowing the investigation of his death without compromising their ongoing investigation into the activities of a drug kingpin. The officer investigating the murder visits the kingpin to ask about Steve's murder. She shows him a photo of the murdered man, but the name across the bottom is Danny Stevens - the policeman's real name.
Other mistake: Grady opens Owen's phone with the wrong passcode. The code is 082007 but he enters 08207.
Other mistake: Juliette and two cohorts need to go from Level 22 down to Level 125. Using the normal circular stairs, it would take several hours if not days to get there. They enter a garbage chute and climb down using a vertical ladder on the side - a very clumsy and slow descent. Yet, they make it in what appears to be a very short time.
Other mistake: When Tom is sitting in the chair reading Ellen Combs' medical/surveillance file, the page he is reading just contains the lyrics from the Ella Fitzgerald song "Someone to Watch Over Me".
