Revealing mistake: The captain's arm that was removed can be seen wrapped in a green screen editing sleeve when he is in the hospital. (00:39:55)
Plot hole: The FBI is looking for a "very tall" guy who has been identified as such by various witnesses and by their own expert due to the entry angle of a fatal bullet wound - 6'5" at least. They send Elena into a bar near the end of the show to meet the Albanian perp who when he arrives is barely average height.
Episode #1.4 - S1-E4
Continuity mistake: When Samuel and Marina kiss for the first time, she leans in towards her left. In the next shot, she's still kissing him, but leaning on her right side. (00:23:45)
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)
Episode #1.1 - S1-E1
Factual error: This is set in 1933. When the killer comes back to his lodgings in episode 1, Lily on the stairs is humming "Somewhere over the rainbow", which was written for The Wizard of Oz in 1939. She also happens to wear bright red shoes, which feels like yet another Wizard of Oz reference. Interesting enough, the subtitles say that she is humming a different song, "Night and day" which she openly sings throughout the series and was already a hit in 1932. (00:44:10)
Continuity mistake: As the US Embassy in Caracas, Venezuela is being evacuated, the ambassador steps into a Black Hawk helicopter with markings 33 and 3016. After her Black Hawk arrives at the Aeropuerto Francisco de Miranda Airport in Caracas, it has markings 60 and 2065. (00:25:48 - 00:29:20)
Other mistake: The shopkeeper hands Danny a Beretta 92fs/M9 handgun with a detached suppressor. To mount a suppressor to the muzzle end of the handgun the barrel needs to be threaded, and this one isn't. Sometimes barrels are threaded and when no suppressor is attached they are protected by a thread barrel cap to protect the threads from dings and bumps. There is no thread cap here either. (00:22:35)
Character mistake: Budd is constantly shown buttoning up his jacket when he exits the limousine prior to Julia exiting. As a PPO, SOP is to unbutton to make reaching his firearm easier, not harder! Also, when he buttons, you cannot see the firearm on his belt at all, even though the jacket is quite tight.
Chapter Twenty-Eight: Sabrina Is Legend - S3-E8
Visible crew/equipment: During the strobe lighting at the very end of series three, with Faustus Blackwood seemingly releasing something evil, it is noticed that during the flashes, it is leaving after effects, showing the shape of the equipment that make the strobe lighting. (00:58:00 - 01:00:00)
Factual error: The gun used to kill Koresh is a Beretta M9A1 (92A1). These were not produced until 2006. The correct pistol would have been a Beretta 92. (00:43:15)
Factual error: Sir John Franklin's wife is consistently addressed and referred to as Lady Jane. Since she only held a title due to her husband's knighthood and not in her own right, she was actually Lady Franklin. Nobody in the circles in which she moved would have addressed or referred to her as Lady Jane.
Fear and Loathing in Beverly Hills - S2-E8
Continuity mistake: In one part of the scene where Joe has Delilah's iPhone and it's ringing, it shows the call with a green answer button and a red decline button, then, it shows it only with a slide to answer option. (00:53:00 - 00:59:00)
