Factual error: In scenes from the oil rig there are shots that show the shore line. This oil rig is supposed to be offshore of Louisiana. However, mountains can be seen in the shots of the shoreline. There are no mountains in Louisiana.
Continuity mistake: When Megan is running late to pick up her daughter and friends from a sleepover, she arrives in the medical examiner car with Peter. The girls walk towards the car. Megan then gets out and introduces herself to the friends. The girls dump their bags on the ground and the two friends go to get in the car. Her daughter stands by the bags and asks 'who are you?!' to Peter. He explains who he is and that he works with her mum. - however in a previous episode her daughter goes to her work place and interviews all the staff, including Peter. (00:17:35)
Other mistake: When Lucy is in the cafe watching the mother and her children, the mother repeats the same dialogue.
Continuity mistake: After Buffy finds Morgan's brain, Willow pulls up Morgan's school file on one of the library computers without even touching the keyboard. One moment the monitor is on the desktop, the next it's showing Morgan's file.

Confinement - S2-E5
Continuity mistake: Ruby asks Ash where the the Kandarian Dagger is. He says that it was confiscated by the police. In the previous episode, she had and used it, and they have not interacted in the intervening time period.
It May Look Like a Walnut! - S2-E20
Character mistake: Rob is having a nightmare, part of which involves the disappearance of his thumbs. When he finds Laura at home, the script calls for him to say, "I want you to help me get my thumbs back," but he actually says, "I want you to help me get my thumb backs." His thumbs are also still there but hidden (you can see a portion of them in one frame of the episode).
Continuity mistake: Ruth is seen in a flashback. The young Ruth has a mole on the left side of her face, as does the adult Ruth. But in one shot, when she is slapped by her father, the mole appears on the right side. (00:20:00)
Revealing mistake: In the episode where Denise tries on her wedding dress Jim leaves the room to go and wash up. As he opens the door to leave the living room if you look down towards the front door you can see Dave stood by the door frame waiting for the next scene.
The Suitcase - S4-E7
Factual error: At the beginning of the episode, the male employees are all discussing James Bond. It is mentioned that 'James Bond goes underwater, he met a girl underwater'. This refers to the plot of the movie 'Thunderball' (it does not occur in the Thunderball novel, nor any novel or film prior to this). The main plot of this episode centres around the Sonny Liston VS Cassius Clay fight in May 1965, and 'Thunderball' was not released until December of that year.
Visible crew/equipment: In the first scene of the episode, a crew member is visible through an open door beside the staircase.
Continuity mistake: On the video of Ian supposedly killing Alison, we see her arm fall to the ground with her "Alison" bracelet visible. But in a later scene where Emily watches Ian put his bag in the athletics room, we cut back to the video and Alison's arm suddenly has a sleeve covering up her bracelet. When we see the video again later in the series, her bracelet is visible again.
Continuity mistake: This is a mistake for the introduction from seasons 2-20 (1991-2009). When Homer screams, he turns round. You see this in a wide shot. There are no boxes to the right of the door in the garage. However, two just appear out of thin air when he runs through the garage. (00:01:50)
Other mistake: The opening credits for season 5 show June coming out of the front door with a pitcher of what looks like iced tea, and calling for Ward, Wally and Beaver who are all working outside. But the door opens by itself as she comes out, and then closes by itself behind her. If the entire family is outside, who opened and closed the door?
Gold Is Where You Leave It - S1-E19
Revealing mistake: Buck lights the fuse and tosses the dynamite-filled barrel at the bad guys. We see the explosion. Unfortunately, after that, we can also see the intact barrel still rolling away in the dirt.
Shoes, Hats, Pickle Jar Lids - S5-E9
Revealing mistake: When Charlie is in the Ferrari, his gets a call from Teddy. When Charlie brings the iPhone to his ear and talks to Teddy, you can see that the iPhone is upside down showing that no one actually called his phone.
Klink for the Defense - S6-E19
Continuity mistake: General Burkhalter is eating Klink's dinner. When finished he places a metal cover over the plate. In the next shot the cover is lying on the table and there is extra food on the plate. (00:15:25)
Plot hole: If the Lady of the Lake walks every night to her room and kills those in her path, why didn't Flora and Miles' parents die in their room by the hands of the Lady in the Lake when they first moved in?
Is There in Truth No Beauty? - S3-E5
Other mistake: In the final scene, Kirk is still in the transporter room, but does not have on a visor when the ambassador transports out. Even if he did, humans can still go mad if wearing one and that's why Spock operates the transporter. Spock has his visor on, but then you see Kirk walk out of the transporter room without a visor and he is not going mad.
Continuity mistake: While Tori is getting her mask removed, another shot shows her sneaking back on stage, but the next shot shows her still getting her mask removed.
Suggested correction: The entire series was set in an alternate history of sorts, so most, if not all, historical "inaccuracies" cannot be regarded as mistakes.
