The Lost Planet of the Gods (1) - S1-E4
Visible crew/equipment: When Apollo has briefed the female shuttle pilots about the the pressure suits, Serina tells him she loves him. Apollo then calls for Starbuck to come with him, and as Apollo walks to the door, take a look at the right side of the fire extinguisher beside the door and you should be able to see the boom mike shadow move. (00:29:55)
The Lost Planet of the Gods (1) - S1-E4
Factual error: Starbuck and Apollo fly into a void and are surrounded by total blackness. This misconstrues the meaning of a space void, which is simply a large area without stars. It does not mean that further-distant stars and galaxies would disappear. They'd still be just as visible as before you entered the void. Even if Starbuck and Apollo were able to leave the galaxy and travel hundreds of thousands of light years into a really big void, they'd still be able to see the galaxy they left behind them.
The Lost Planet of the Gods (1) - S1-E4
Deliberate mistake: At the beginning, the scene in which Baltar is granted a Cylon base ship is recapped from the end of "Saga of a Star World." Only the lines are edited into a completely different order than they were before.
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)
The Lost Planet of the Gods (2) - S1-E5
Continuity mistake: During the wedding ceremony, Adama states he is about to recite the most powerful words in the universe. He then says "Under the eyes of God, bound by the symbol of the faiths of the Lord of Kobol.". But in doing so, the actor forgot that in the show's "universe", humans believe in multiple gods, referring to them as the "Lords of Kobol" and "The Gods". (00:17:05)
The Lost Planet of the Gods (2) - S1-E5
Revealing mistake: When Galactica arrives at what they believe is the planet Kobol, Adama, Apollo and Serina all go down to the surface. As they approach the ruins in several shots from behind, the three are obviously, almost laughably, replaced by stand-ins. Adama's white hair is enormous, almost helmet-like, and Apollo's is nearly as bad. Serina's famously long, rump-length hair is suddenly much shorter and she has no gun on her right hip. When the three are seen entering a shot from the left, the normal actors are back, including Jane Seymour's abundant brown hair and her gun. The stand-ins appear again later, in all the exterior shots obviously filmed in Egypt. The normal stars were filmed on studio sets. (00:18:20)
The Lost Planet of the Gods (2) - S1-E5
Visible crew/equipment: When Apollo leaves the chamber after Serina dies, you can see the shadow of the camera moving on the floor as it moves closer to the door. (00:44:35)
Audio problem: As Apollo's Viper is under attack by several Cylon Raiders, he radios Galactica, saying "Galactica, Recon Probe 3. Where's Blue Squadron? I'm running out of time." A few shots later, aboard Galactica, we hear Apollo's voice over the radio, saying "Where's Blue Squadron? I'm running out of time." twice, back-to-back. It's a reuse of the audio from the earlier scene. We hear the exact same audio a total of three times in less than 45 seconds. (00:03:00)
Factual error: When Apollo runs out of fuel in space, he still controls his ship using the joystick as if gliding in an atmosphere. No thrust source is visible nor audible- only the sound of non-existent air rushing around his ship. (00:04:30)
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)
Continuity mistake: Apollo and Vella sit in front of the fire and she tells him about her late husband. In the two-shots, their shoulders are touching. But in all the close-ups, it's apparent that they're much farther apart and turned to face each other rather than sitting side by side. (00:16:15)
Continuity mistake: When Marcos places his bet, he has a gold mug to his right on the table. When the shot reverses to show Lacerta, the mug has vanished. The mistake alternates, repeating itself throughout the entire scene. (00:23:20)
Revealing mistake: Re-used footage causes the lupus running toward Puppis to make the exact same leap twice. (00:26:45)
Continuity mistake: When Tigh enters Adama's quarters, the photo frame holding Apollo and Athena's pictures is sitting on the desk. Next shot, Adama has it in his hands. Cut again, it's back on the desk. (00:28:35)
Continuity mistake: When Bootes throws a tantrum at the bar, he knocks two hats off the bar and his mug falls over directly in front of him. When the shot changes to an angle from behind him, his mug is standing and one of the hats is back on the bar. (00:36:30)
Factual error: Apollo tells Boxey they're leaving their star system and entering "a whole new galaxy." Wrong. Throughout this episode, the writer confuses solar/star systems and galaxies, which are vastly (literally) different things. Even with hundreds-of-times-faster-than-light drives, Galactica's fleet would need thousands of years to cross between galaxies. (00:02:15)
Other mistake: The very first shot of the episode shows the Galactica is coming through a cloud of "asteroid dust". The ship is intermittently obscured by the black dust, yet the stars in the background remain perfectly visible- barely a flicker as the dust passes through the shot. (00:02:40)
Continuity mistake: When Apollo asks Adama if he was ever like Boxey, Adama replies "Worse". The two characters are standing well apart, each leaning forward with both hands on a railing, shown from the front. When the shot changes to show them from behind, Adama has his arm around Apollo, hand on his shoulder. (00:03:45)
Continuity mistake: Starbuck and Cassiopeia stand looking out the window. In the wide shot, her back is to his front, his arms around her waist. In the close-up shot, they are suddenly face-to-face, her hand toying with the trim on his cloak. (00:05:15)
Continuity mistake: In "Saga of a Star World", it's established that the Cylons are entirely robotic. Their creators, a reptilian race also known as Cylons, were made extinct by their robots millennia ago. Yet, when Omega reports that life signs have been detected, Apollo asks "Cylons?". Apollo is the character that previously explained their history, so he knows Cylons aren't life forms. (00:06:55)
