Other mistake: The battle droids - including the commando droids featured here - habitually have two broad fingers and a thumb. So how can a commando droid squeeze itself completely into clone trooper armor without its broad fingers tearing open the gloves, since it can't separate its fingers?
A New Day in the Old Town - S2-E1
Other mistake: The killer from another dimension shape shifts into the appearance of the victim, leaving the victim's body. But it transforms into Charlie's appearance and leaves behind its former female nurse shape, hiding Charlie's body to dispose of later. It would have needed to transform from the nurse shape, not out of nothing. The original nurse's body was not at that location.
Suggested correction: The shapeshifter transformed into Charlie using his dead body which it then disposes of at the end of the episode.
But when the shapeshifter transforms into Charlie, he shouldn't be leaving the body of the nurse behind since he had killed the nurse before entering the hospital and transformed there into her. The only dead body in that last scene should be Charlie's.
Other mistake: Gus is talking to his employee about the twins while writing something on a clipboard. However, he is using the opposite end of the pen and just pretending to write. (00:14:40)
Other mistake: The bullet they pull out of Bobby is the entire bullet, casing and all, not just the slug.
Other mistake: Carrie the assistant brings Lisbon and Jane to Stutzer's office. She swipes her card to open the door. However, she does this upside down, swiping the bar-code instead of the black magnetic strip, on which she is holding. (00:09:30)
Other mistake: Season 2, Episode 20: "To the Lighthouse" - In the flashbacks to the jungle, John is considerably younger. Sarah however, is not. Adults don't change nearly as much as a child would in the same time period, but this is a pretty big jump back in time. John is only a child in the flashbacks, putting Sarah in her mid to late 20s. Yet she still looks 35 and even has the exact same skin and facial structure.
Home for the Holidays - S11-E1
Other mistake: Only one set of prints were said to be on the garrote but in the last episode of season 10 Graham handles the garrote before handing it over to the murderer without wearing gloves. So there should have been 2 sets of prints.
Other mistake: When Uther takes Excaliber from Merlin while preparing for his duel with the black knight, we see that Uther is left handed. And he is left handed while writing. He tests the balance of the sword with his left hand, and in fact wears his sword on his right hip in all other episodes. Once he puts his helmet on and begins his duel with the black knight he suddenly becomes right handed.
Other mistake: During "My Freeze Ray", there's a shot where Billy, Penny, and several other people open doors to the laundry machines in sequence. When Billy opens the door to his machine, you can see the reflection of everyone else just standing there, waiting for their cue to walk forward.
Other mistake: When Beast is flipping through his notes to try to determine what caused the explosion at the mansion a year earlier, you can see all the pages are blank. (00:13:50)
Other mistake: When the team is in the grocery store, they rewind the security videotape (they play it backwards). They stop it at the last activity, when a man comes in and chainsaws his own head off. The body (and head) have gone blue/purple, and since everyone else died the previous night, we can assume that he cut his head off around 12 hours ago. At high speed reverse play, the time they spent rewinding would be only around 10 or 15 minutes of recorded time. (00:32:50)
Other mistake: The song 'Happy birthday' by 'Altered images' wasn't a hit until the autumn of 1981, and couldn't have been played at the boat party.
