Revealing mistake: Despite them wearing masks at the end you can still see a lot of the amazons are being played by men - you can see hints of beards.
Continuity mistake: The attachment to the minisub is inconsistent. It is an open hook first then as it's being lifted it becomes an enclosed shackle looking quite different. Plus a figure now appears on the roof. Ben Gazzara has just gone below. (00:57:42)
Revealing mistake: When Frigga shoots a client in his house you can see the outline of the fake blood packets under his shirt.
Continuity mistake: Some scenes show the actresses in their yellow prison dresses getting dirty, yet a minute or so after this, they're clean again.
Continuity mistake: Vicky is in her office, wearing glasses, until a girl knocks on her door and walks in, and the glasses have vanished.
Visible crew/equipment: When the camera zooms in on Sebastian as he is suspended dead by the snake charmer's rope, a visible wire can be seen suspending him in the air. (00:47:25)
Continuity mistake: Visiting the prostitute scarred with the sharpened coin, Rizzo looks at her in her hospital bed. In her close-up she is holding the bed sheet with both hands, but in the wider views before and after, nothing of the sort happened, her hands were off the sheets. (00:18:00)
Continuity mistake: When the prisoners in the confinement holes talk clinging from the bars at the top, Jim Brown's hands are one bar apart in the overhead shot, 2 bars in close-ups. (00:00:50)
Audio problem: The slave recruiter in the village shoots Shaft and kills his bodyguard. The Luger gun he is using has a suppressor, but the noise it makes is the noise of a normal, not 'silenced' gun. (00:56:55)
Continuity mistake: Victor Pivert is in full road rage mode as he is waiting at a road stop after skipping most of the line speeding through the emergency lane. As he bickers with his French compatriot, he hammers his horn initially with the right hand, then after a pause he starts hitting it with his left hand in a side view, which turns instantly into his right hand at the cut.
