Continuity mistake: During the firefight in the detention corridors, the blaster holes in the metal wall Jenna's firing toward keep changing, sometimes disappearing altogether. One of them is created twice, appearing as the troopers duck out of sight, vanishing and then reappearing in the same spot when Jenna fires again. (00:36:00)
Space Fall - S1-E2
Continuity mistake: A large white cushion, knocked askew when Blake tosses Avon over the flight couch, has righted itself a few shots later, as Avon gets up from the deck. (00:46:25)
Plot hole: Avon delivers his summation of the crimes and the murderer's identity to the Ortega's crew - with his back turned to the guilty party the entire time. This gives the killer ample time to pull a gun on them. But it's also egregiously out of character for Avon, whose suspicious nature bordered on paranoia and would never have allowed him to be so careless. (00:42:25)
Time Squad - S1-E4
Continuity mistake: The alien hiding in the hold throws a large blue tool at Jenna. It strikes her on the back of her right arm. But in the next shot, she's holding her left arm, and Gan later treats a bruise on her left arm, nowhere near the spot where the tool hit her. (00:27:45)
Deliberate mistake: Because Stephen Greif tore an Achilles tendon playing squash, a stand-in had to complete his scene with Servalan in Ensor's underground complex. The result was a very odd segment in which we hear Travis' voice (pre-recorded by Greif) answering Servalan's lines, but never see him - except for an awkward shot of shuffling, black-booted feet that are all-too-obviously not Greif's.
Visible crew/equipment: When Blake and the landing party are on the flight deck, preparing to go down to the planet, something black intrudes on the left side of the screen during a shot of Avon on the flight couch. (00:08:50)
Revealing mistake: As Liberator approaches it, the planet changes color. (00:08:05 - 00:13:40)
Visible crew/equipment: When Jenna tries to call Gan and Vila from her flight deck station, part of a piece of equipment is sticking out into the lighted corridor to her left. It's still there later, when Gan walks through the opening, but it's gone a short time later. (00:06:45 - 00:13:15)
Factual error: Zen refers to the objects encountered at the beginning of the episode as "meteorites". In space, these objects are known as meteoroids. When they enter the Earth's atmosphere they are called meteors, and when they hit the surface of the earth they are called meteorites.
Continuity mistake: Liberator's orientation relative to the space station changes. As viewed from inside the administrator's office, the ship is "parked" parallel, with its port side against the station. But in the subsequent exterior view, Liberator suddenly has its bow pointed directly at the station instead.
Factual error: Travis fails Astronomy 101 with the line, "Blake - the other patrols have pushed him into this galaxy." That should be star system, not galaxy. B7's ships weren't capable of intergalactic travel. Not just a character mistake, either. Travis is a trained Space Commander, and should definitely know the very big difference between a solar system and a galaxy, even if the scriptwriters - and people who keep miscorrecting this error - do not. (00:03:10)
Visible crew/equipment: Sarkoff holds his Plexiglas/Perspex butterfly case up to admire it, and captures a perfect image of one of the set's large rectangular light reflectors. (00:28:15)
Visible crew/equipment: When Sarkoff puts a record on his antique phonograph, the metal desk behind him reflects a camera dolly rolling by. (00:25:50)
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)
Visible crew/equipment: Ah, the hazards of shiny metal set walls. When the doctor closes Avalon's cell door, there's a hazy but discernible view of the camera and a moving film crew member. (00:30:30)
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)
Visible crew/equipment: At the end, when Blake says "The other end is connected," the boom shadow crosses Avon's face. (00:46:50)
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)
