Revealing mistake: As Jenna leaves the flight deck and heads down the access corridor, a camera is briefly visible just to the right of the hexagonal entryway. (00:09:20)
Continuity mistake: Villa is carrying Orac and Soo Ling is about to play the quick draw game, cut to the bridge and Dana walks over to the captain's chair to contact Avon and the top of Orac can be seen in front of her.
Audio problem: Just as Zen is reporting that it can find no stars for navigational reference points, something crashes very noisily off screen. No, it isn't the arriving Dayna's clunky shoes. Much too loud, unless she's throwing them at something.
Character mistake: Whilst brutalising Pinder, Egrorian asks if he can feel his humerus grinding against his radius, but the bones in the forearm are the radius & ulna. The humerus is the single bone from the shoulder to the elbow.
Audio problem: Just before Avon reveals Orac is on the shuttle, you can hear his operating noise. If we can hear it, so should Vila.
Plot hole: Servalan & Egrorian discover their Orac is a fake when it continues to light up and make noises after the key has been removed. But this makes no sense; the key functions as it should during the demonstration. Even if it's to do with no longer being connected to the real Orac, with the shuttle getting further away it shouldn't function at all.
Plot hole: The drama on the crashing shuttle comes from the idea that a speck of Neutron material is super-heavy. Yet in the laboratory, Egrorian states that 8 Neutrons make up the core of the Tachyon Funnel. This would make it so heavy it would probably sink through the entire planet, yet Pinder, Vila & Avon wheel it about like the aluminium prop it is. And if the Neutrons are held in some sort of anti-gravity field, that would require an enormous amount of power, but Pinder uplugs it at Avon's request.
Suggested correction: Neutrons and Neutron material do weigh differently. 8 neutrons would weigh 8 atomic mass units - immeasurably small. Neutron Material on the other hand is comprised upon trillions upon trillions of neutrons compressed by gravity into a very small volume (and is the theory behind black hole formation). A microscopic fragment of Neutron Material would indeed have a very very large mass, but too massive even for Avon to move. That and the fact that Neutron Material comes from a Neutron Star raises the question of how it was extracted, cooled and moulded into a lump of perspex.
Continuity mistake: After revealing Avon & Soolin are still alive, there is no magazine in Avon's gun.
Continuity mistake: Dayna plants the grenade by the right-hand upright of the ladder. Yet when it detonates you can see the blast is to the left and in front of the guard; presumably to prevent it from going off right in the stuntman's face.
Plot hole: During the entire standoff between Blake & Travis, there is a Federation guard with his hands on his head. Yet when the scene first begins, no-one else is and Blake is not holding a weapon on anyone. Neither has he revealed his play with the virus at this point. After he has done so and left, the same guard still has his hands up. Finally, after Travis has secured the virus, the guard STILL has his hands up.
Revealing mistake: The muzzles of the the crew's guns are usually empty, but when they need to actually fire them, you can see a black insert sticking out which is the little pyro charge.
Continuity mistake: During the punch-up with Cancer, Tarrant's holster is missing.
Continuity mistake: When they shoot open the crate containing the gold, Avon is on the left & Keeler on the right. Avon fires and we see the right-hand lock explode, then Keeler shoots and the left-hand lock pops.
Revealing mistake: On Scorpio, the barrel of Avon's gun is bent.
Continuity mistake: After Scorpio has landed on Xenon, the lift rotates 180 ready for launch. Yet after Pella boards the ship, it is seen rotating again.
Character mistake: The first time they go into the hold, Avon calls Keeler "Kilo"
Character mistake: Gunsar refers to his predecessor as Maverick, but on the recording Nina calls him Marvick.
Headhunter - S4-E6
Character mistake: Tarrant says they can't land the ship without Slave. Yet in 4-1 "Rescue" he questions the competency of the automatic systems and offers to land the ship himself.
Headhunter - S4-E6
Plot hole: The 6 second countdown lasts much longer than 6 seconds.
