Revealing mistake: The double-bladed axe one of the Decimas uses to attack the station windows is wobbling as he strikes with it. Small wonder he's not getting far at breaking in, with a weapon made of rubber. (00:22:30)
Space Fall - S1-E2
Revealing mistake: Just after Avon slips into the access tunnel and the prisoners close the hatch behind him, the star field in the window shakes and wobbles. (00:17:45)
The Way Back - S1-E1
Revealing mistake: When Tel Varon walks in front of the wall screen in the justice data center, a flash of gibberish lettering and a blue matte line both appear briefly above his head. (00:36:40)
Time Squad - S1-E4
Revealing mistake: Jenna moves down the corridor on her way to the hold with her Liberator gun in hand. The weapon lights up and flashes several times, even though she isn't firing it. (00:37:25)
Space Fall - S1-E2
Revealing mistake: The boom shadow is visible moving swiftly across the actors' heads when Avon says, "You've got an army of five, Blake." (00:16:40)
Space Fall - S1-E2
Revealing mistake: The uppermost of the flight consoles of Liberator isn't fixed down in this episode, and wobbles almost every time it is touched, and not just small wobbles. Watch for the 10 seconds or so after Jenna says "Eventually I might just be able to get her to start and stop", and you'll wonder how she didn't knock the entire prop off whatever it's sitting on and onto the floor.
Cygnus Alpha - S1-E3
Revealing mistake: Stock footage of the London's launch from Earth is run in reverse when it lands, supposedly 8 months later, on Cygnus Alpha. What are the odds that a remote penal planet will have a launching pad with configurations, lights, buildings and background terrain all completely identical to the launch stage on Earth? (00:10:20)
Suggested correction: Airports resemble each other, prisons resemble one another. So do hotels, shops etc. Why isn't this possible?
Revealing mistake: When the Federation troopers blow open the interrogation room door, you can see a brief glimpse, through the smoke, of the thrown sledge hammer that was used to make the door fall in. (00:48:15)
Space Fall - S1-E2
Revealing mistake: Whenever the prison ship fires its engines, the smoke trails travel to the top of the screen, as smoke does in an atmosphere. In space however, it should billow away from the engines in a more or less straight line.
Space Fall - S1-E2
Revealing mistake: Aboard the London, as Raiker opens the rec-room door, a boom mike shadow moves across Avon's face. (00:04:30)
The Way Back - S1-E1
Revealing mistake: When the prison ship launches, the cloud of smoke reveals the black wires that are lifting it up.
Cygnus Alpha - S1-E3
Revealing mistake: The high priest Vargas is wearing a nice new pair of decidedly 20th century basketball shoes under his robe. We even get a good close-up of them at one point. (00:49:15)
Revealing mistake: As Liberator approaches it, the planet changes color. (00:08:05 - 00:13:40)
Revealing mistake: A very poorly executed special effects matte causes the star patterns behind the 3 pursuit ships to slide in opposing directions at the same time. (00:42:35)
Revealing mistake: When the fight begins in the detention block and the trooper runs away from Jenna down the hall, two large blaster holes appear in the wall he runs toward - before the first shots are fired. (00:34:45)
Revealing mistake: When the "phibian" lizard creature attacks Servalan, note the claw that grabs her leg: it is obviously made out of soft fabric and visibly bends as it latches on. (00:24:05)
Revealing mistake: When Blake hastily slaps at the oxygen vent control to close it, the knob breaks off, drops to the floor and bounces noisily away. (00:07:25)
Revealing mistake: The explosive collar supposedly locked around Blake's neck is undone and hanging open just after he's thrown into the cell with the other prisoners. (00:33:45)
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)
