Continuity mistake: Sabrina is in New York and she stays at Tuxedo Hotel; her room number is 325. However in a close shot of the key chain, it seems that she stays at another hotel (something like Zarac Hotel), while her room number is 1207. (00:20:30)
Chapter 14 - S2-E4
Continuity mistake: When Palpatine and the others exit the elevator, a rear shot of their group shows that one trooper holds his rifle, but the other is missing his rocket launcher. But when seen from the front again, this trooper has the very obvious launcher hanging from his shoulder, behind him. (00:40:00)
Other mistake: When O'Neill first goes to visit Teal'c in his cell the symbol of Apophis on Teal'c's head is upside down.
Visible crew/equipment: After Spock asks Scotty if there's enough battery power to electrify the exterior of the ship, Spock tells everyone, "Get to the center of the ship. Don't touch the plates. Be sure you're insulated," and just as Spock turns in the rear compartment we can see the edge of the shuttlecraft set behind Spock.
Flipper and the Bounty - S2-E13
Visible crew/equipment: After Bud wakes up all alone in Bligh's cabin, he soon realises all the doors are locked. Then, just as Bud rushes over to the stern window (particularly the second time), a seated crew member is visible at the bottom right corner of the screen; we can see the movement of a leg and two hands (so, it's not a mannequin).
Other mistake: At lunch, when Sam is using a spoon to shape his mashed potatoes on the tray, his right arm clips through the tray just as he says, "Maybe I should clear out the east wall like this." Then, when Sam says, "Maybe I should fortify the south side first," he's using the spoon to move the mashed potatoes on top of the tray, but his arm and spoon are under the tray, so it looks as if the potatoes move on their own. Additionally, when Sam states that he's so confused, the spoon held up in his right hand appears to vanish in the next shot.
The Contest - S1-E24
Other mistake: When Tom unzips the backpack to collect everyone's devices, he adds a few devices that belong to Ben, and as Tom drops in sneaky Ben's last device, watch as the backpack zips itself shut mid-shot, all on its own. (00:04:32)
The Alexander the Greater Affair (1) - S2-E1
Character mistake: When Alexander organizes the human chess game in his courtyard, the "pieces" stand the wrong way on the board, with a dark square in the lower right hand corner. That corner is always a light square. (00:22:50)
The Crab with the Golden Claws: Part 2 - S1-E2
Other mistake: The newspaper article that features Tintin and Captain Haddock at the end of the episode is a flipped shot, as shown by the text that has been reversed. (00:43:35)
Triumvirate of Terror! - S3-E8
Continuity mistake: When Joker zaps Wonder Woman and her mother, they are both standing in front of their thrones and fall forwards. But when Wonder Woman stands back up, her mother, still unconscious, is suddenly off to the side and behind the thrones. (00:11:35)
Iron Forged in Fire: Part One - S1-E1
Continuity mistake: As Rhodey and Tony are walking by a building, Rhodey tells Tony to not worry, as in two years he can fire Stane. The first view shows their shadows directly under them, like the sun is at its zenith. It then cuts to a shot from above their heads and now their shadows are elongated and cast on the wall beside them. (00:09:35)
Rising (1) - S1-E1
Continuity mistake: When they first arrive on Teyla's planet, the DHD is close to the gate. When the wraith attack, the DHD is much further from the gate.
Continuity mistake: When Tommy is escaping into the mountains to try and help, a small bit of his jacket tears off onto a tree branch. MacGyver later sees it, but the branch that the torn piece is on looks entirely different. (00:21:10 - 00:22:10)
Revealing mistake: When Syd's Dad rescues her in the car park, he starts shooting at the other car. After firing one shot the slide of his gun locks back (indicating it's out of bullets), but when the angle changes he carries on firing with no problems. (00:43:20)
The Odyssey - S1-E14
Continuity mistake: When Wilson jams the pistol in Oliver's face, Wilson is holding the gun in his right hand. When the shot changes, it flips - he is suddenly holding it in his left hand, and his previous un-scarred left eye now has some scrapes around it.
Visible crew/equipment: When Zaphod says his first line "I certainly didn't survive.", you can see the person who plays his third arm standing behind him.
Continuity mistake: The package Nigel holds in his arms near the beginning of the episode completely changes between shots.
Dear Diary - S4-E20
Continuity mistake: While it's forgiven that the Generals usually have subtle changes through episodes and the series, in this episode we see a General with extremely inconsistent graphics when Bo and Luke deliver the counterfeit money to Winston. The 0 is off and the bottom of the 1 is extremely long.
Continuity mistake: When Starfire asks what is the Maximum 7, her, Robin, Raven, and Beast Boy are standing together looking at Cyborg in a wide shot. Raven is slightly behind Beast Boy but to his right, and her body is facing to her left. But then it cuts to a close shot from in front of the Titans and suddenly Raven is on Beast Boy's left and right beside him, with her body facing her right. (00:03:50)
