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)
Other mistake: All the Greek name variants are used over the Latin ones - including even "Odysseus" over the more familiar "Ulysses" (who is the same person). However when the story of Actaeon comes up, it's suddenly the goddess "Diana" that he saw. But all the gods have their Greek names, so that should be "Artemis." (As indeed is used in episode 2).

Visible crew/equipment: Right before Anissa and Tavon are attacked by Khalil, the shadow of a camera can be seen on the ground in the bottom right corner of the screen as they approach the path.
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)
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)
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)
Factual error: After Dr. Austin directs the anesthesiologist to urgently start phentolamine intravenously to address the patient's hypertensive crisis on the operating room table, the anesthesiologist is seen quickly rolling the clamp on the line, purportedly to make it run faster. The clamp however is being rolled in the direction to close off line's flow. (00:20:20)
Continuity mistake: Just before the portal opens where Sonic comes out by a water fall, you get a good view of the ground around where he comes out at and there are no holes. But once he emerges, he looks around and then looks down and suddenly there are large holes that become what he focuses on. (00:00:25)
Visible crew/equipment: In the final minutes, it is possible to see a drone flying between the camera's point of view and the subject being filmed, the DEA agents' van going into Mexico. Likely filming equipment, but even if recreational it's hardly appropriate for the 80's. (01:06:30)
Continuity mistake: At the diner when Tsunoda and Retsuko are talking, Tsunoda pulls out a red phone with a white heart on it from her purse. In the close up she is pulling it out with her left hand and the phone is horizontal with the heart on its side. It then cuts to a wide angle and suddenly she's holding the phone upright with both hands.
