Continuity mistake: In a wide shot, Apollo is inspecting an air rifle. As the wide shot ends, he holds the rifle wrapped by both hands. When the close-up shot starts, the gun is on its side, held by his right hand while his left is removing the air cartridge. (00:11:40)
Saga of a Star World (2) - S1-E2
Continuity mistake: When Apollo, driving the land rover, is explaining the Cylons' origin to Boxey, the position of the mouthpiece on his headset changes slightly as the camera angles reverse.
Continuity mistake: When Aurora and her companion are picking up the guns from the closet, you can see the closet contains two racks with several guns on them. At first they empty the upper rack of guns. When it cuts they empty the lower rack, but then the guns suddenly have reappeared in the upper rack. (00:13:30)
The Magnificent Warriors - S1-E10
Revealing mistake: Due to repeated film footage, Sectar's full moon rises on the second night with the exact same, very distinctively-shaped cloud bisecting it. (00:11:45 - 00:26:10)
Revealing mistake: Starbuck is romancing both Cassie and Athena in different rooms aboard the Rising Star. Odd that both rooms have the same wrinkle and tear in the wallpaper just under the window. There's also, in both rooms, what looks like a black thumbtack repairing the glitch. (00:08:25)
Revealing mistake: Re-used footage causes the lupus running toward Puppis to make the exact same leap twice. (00:26:45)
The Lost Planet of the Gods (1) - S1-E4
Visible crew/equipment: After the scene when Apollo and Starbuck go into the decontamination booths, it cuts to Adama, Boomer and the doctor talking. When they walk from the bridge and Adama says "I want everyone who's been in contact with Jolly and Boomer under strict quarantine", you can see the boom mike shadow moving on the wall to the right of the screen. (00:21:40)
Continuity mistake: When Apollo asks Starbuck "Where's John", Starbuck answers as if he knows who John is, yet Starbuck never asked nor was told John's name. (00:32:30)
Continuity mistake: When Apollo speaks with Adama, close-ups show the left side of Apollo's face is mostly shadowed while the right is well lit. In the wider shots, the left side is very well lit. (00:44:30)
The Lost Planet of the Gods (2) - S1-E5
Continuity mistake: When Serina rings the bell and says "This round's on me", she lets go of the rope. When it cuts she is still holding the rope. (00:05:55)
Plot hole: After crashing on the planet, Starbuck's pants are shown torn open on his right thigh which is bleeding significantly. The child warriors find him and bandage his wound. When Boomer and Apollo arrive to pick up Starbuck, they give him a clean uniform. In the next scene, he is in that uniform, but his injured leg is wrapped in bloody bandages over the new pant leg. It seems unlikely he'd put the fresh pants on, then bandages. (00:44:40)
The Living Legend (2) - S1-E13
Revealing mistake: As the gold Centurion Cylon approaches the camera, some very obvious human fingerprints litter the frame around his "mouthpiece"- as if left by a crew member that helped the actor put it on. (00:15:45)
The Gun on Ice Planet Zero (1) - S1-E8
Plot hole: The borrowed (oh, all right, ripped off) plot of "The Guns of Navarone" does not translate well here. The premise, that the rag-tag fleet must pass through the "narrow corridor" guarded by the pulsar gun, is ludicrous. We're in outer space here. Outer space is very, very big. We can fly around one lousy little planet, no matter how many Cylons are "herding us" toward it.
The Living Legend (2) - S1-E13
Revealing mistake: As Pegasus approaches the two forward base stars, she is shown from the rear of her port side, moving away from camera. The shot is a reversed image of Galactica (her name is backwards on the landing bay). After the vipers clear a path for her, the same shot is flipped again, so that Galactica reads properly, despite the shot purportedly being of Pegasus. (00:43:55 - 00:45:05)
The Gun on Ice Planet Zero (2) - S1-E9
Audio problem: On their way across the mountain toward the pulsar station, Wolfe draws his gun. Apollo says "The Galactica is the only ship in the galaxy that can protect you", then he pauses for a second. Right before the shot cuts, his mouth continues moving but no voice is heard. (00:30:05)
The Living Legend (2) - S1-E13
Revealing mistake: The shots of the exploding containers in the very modern looking Gamoray are a reuse of shots from the episode "The Young Lords", evidenced by the obvious castle in the background. (00:17:50)
Plot hole: The General informs the President that the Eastern Alliance has just launched its missiles. But the General has been sitting there throughout Apollo's speech with no communications device. So he couldn't have known that the missiles had been launched. (00:36:40)
Greetings from Earth (2) - S1-E20
Revealing mistake: Just before Commandant Leiter is told that all three ships have landed on Paradeen, a shot of the Eastern Alliance ship shows very visible guide wires holding up the model. (00:13:40)
The Lost Planet of the Gods (1) - S1-E4
Visible crew/equipment: When Boxey is playing with Muffit, and Muffit plays dead, you can see a black tape marker by their feet. The marker remains there for some shots, then it's gone. Later, when Apollo and Serina argue about her training to be a pilot and Serina says "He doesn't get a report on every cadet in the fleet", Apollo walks towards the bed. There is another black tape marker where he place his foot, but it wasn't there in earlier shots. (00:23:30 - 00:24:55)
Revealing mistake: When Robber starts shooting at Apollo and Boomer, it's comically obvious that the two warriors have been replaced by stunt doubles that bear almost no resemblance to the actors- most notably as they run for cover. (00:32:55)
