Other mistake: When the kids are playing "Carry On Wayward Son," there are no notes on the TV in the one area. However the boys play the notes there and get it right.
Other mistake: The Monster appearing in the pilot and causing the turbine to explode is a mistake (not trivia). This is actually an artefact of poor CGI effects that was left in the show in error. It was confirmed by the producers. You can see it best here: http://www.lostpedia.com/wiki/Image:Turbine_Explosion.gif.
Episode #1.1 - S1-E1
Other mistake: When detective Campbell is making his speech to the officers, the board behind him has dates ranging from 1966 - 1975.
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?
Other mistake: Leonard says he had a growth spurt after his high school prom. In "The Cooper-Hofstadter Polarization" he told Penny that he still had all his clothes he owned since the eighth grade, after his last growth spurt.
Other mistake: During the battle near the end of the episode, Sisko is heard saying, "Locking onto the lead ship" but he gives the firing order to Bashir, who is seated at the helm. This implies that the targeting controls and firing controls are at separate stations, which makes no sense.
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.
Other mistake: During the Vagina Monologues show, the pair of legs casts a shadow but the microphone stand doesn't. (00:00:45)
Other mistake: When the train stops Godfrey gets off to relieve himself but when he is climbing back in to the carriage the train appears to be already moving at speed because the background projection started moving too early.
Stephanie Plays the Field - S4-E22
Other mistake: It looks like she has earring holes. Didn't she get her ears pierced later on in the series?
A Quiet Day in Dodge - S18-E19
Other mistake: Festus returns from catfish fishing carrying a gunny sack full of fish that is bone dry when it should be dripping wet or at the minimum damp from the fish.
Other mistake: When Rob dials the radio station, he dials the phone number and then looks it up in the phone book. He covers for himself, and then has a hard time keeping a straight face afterwards.
Suggested correction: The part is Rob checking to see if he had the right number.
Marco Polo - S1-E4
Other mistake: In episode seven, Kublai Khan refers to backgammon as a game of cards....obviously he's not an experienced backgammon player.
Other mistake: When Billie visited Georgia's grave in Salem, she acted as if the baby was buried there, yet, Billie should know that the coffin buried is just a bunch of rocks and the real Georgia is buried where Earl, Wayne, and their mother live by the bayou. Billie lied to Bo about Hope being the cause of their baby's death and buried the rocks in the coffin to make it look like the baby had died after her fight with Hope, rather than before.
Other mistake: The tenant board member tells George that Mr. Eldrige in apartment 8C has decided he wants the new apartment. However, the new apartment in question has a 3-digit number - 808 I believe. This indicates that the building would not have single digit numbers and letters (Such as 5E, 8C, etc.) as part of its numbering system.
Other mistake: When they are showing the rap sheets for the Cambodian man, the race on the sheet says Caucasian when he is Asian, and for the African American man, the sex says "F" when he is male.
Alter Boys - S2-E6
Other mistake: In the scene where Grissom is talking to the coroner about the man who was shot and strangled with his tie, you can see the actor that played the body breathing. (00:07:30 - 00:08:00)
Careful What U Wish 4 - S1-E14
Other mistake: During the scene after the fund raising dance when Lucas offers to take Hanna home, she calls him Ian when she says that she is going home with Emily and Spencer. Even if she says "I kind of promised them", the subtitles say Ian.
Other mistake: In the episode "It's About Time!", near the end of the episode after they get back, when the camera zooms in on Phineas and Isabella, Isabella's face is gone - only her eyes remain, but after the camera zooms out her face is back.
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.
