She's Leaving Home, Bye Bye (1) - S3-E1
Continuity mistake: In this episode, it shows Brock and Reba moving into the house the show is set in and Kyra is mad about it. In episode 1-22, Reba flashes back to Cheyenne in the same house much younger than Kyra going into kindergarten. The houses should have been different.
Continuity mistake: Marshall Dillon buries an outlaw at Sarah's place. He installs a wood cross at the grave. Sarah comes out and they talk. When she leaves, the scene cuts back to Dillon and the cross is missing.
Continuity mistake: At the end of the episode, the Mercedes S class that is burning is not the same car that Castle drove previously in the episode, it's an older model one. Either it's a mistake or has to do something with the plot resolution, decide yourselves...
Continuity mistake: When the Hulk throws the tire during his second transformation, the first shot shows a horizontal trajectory but the second shot shows a 45 degree angle trajectory, which makes the tire land much further than expected.
Continuity mistake: When Johnny, Roy, and Captain Stanley are rescuing the people trapped inside Olive View Hospital, they are wearing distinctively marked SCBA tanks on their backs, and when all three firemen exit the doorway, Cap is wearing an entirely different tank, and the tanks that Johnny and Roy are wearing have been switched. Then when Johnny jumps off Engine 82, his tank differs again, and when he walks over to the Battalion Chief it's changed yet again.
Continuity mistake: In season 1 they are tracking leopards but when they take a cub for the cure it's clearly an African serval kitten.
Continuity mistake: During the "Nibblin' with Nimbus" scene eggs suddenly appear in the pan. (00:17:47)
Continuity mistake: Carrie Matheson leaves her sister's house in a Jeep Compass with her daughter. When she arrives at her destination, she is in a newer model of the Jeep Compass (the front indicators are different).
Continuity mistake: When Hook comes to see Emma at the sheriff's station, his earring disappears when she kisses him goodbye.
The Austere Academy: Part Two - S2-E2
Continuity mistake: In season 1 whenever count Olaf's tattoo is shown, it is always on his inner left ankle (the reptile room part 2, Mr. Poe wipes the makeup to reveal it on the inner ankle, and In the Wide Window part 2 when Sunny chews through the broomstick and Olaf's lag is revealed it is also on the inner ankle. In this episode, after Sunny loosens the laces on Olaf's shoe and the Baudelaires defeat Olaf in the arm wrestling, the tattoo is on the outside left ankle.
White Light - S2-E2
Continuity mistake: When citizen Z is searching for zombies, he approaches a door holding a pistol with an under-barrel attachment. When he goes through the door, the attachment has disappeared. (00:01:05)
Continuity mistake: When Agent Wells drives the van filled with bombs out of the parking structure both back doors of the van are open revealing the bombs, in the next shot both doors are closed.
Episode Nine - S1-E9
Continuity mistake: When Barnabas enters Josette's room, the door is painted white. When he leaves and Natalie follows, the door has changed to varnished wood. (00:21:15)
Continuity mistake: When Charlie Epps is writing a quadrillion on the whiteboard, the writing alternates between shots. Most noticably when he first writes it down, there is a significant downward tendency of the 000 groups. In the next shot, they are pretty much horizontal. Also the shapes of the commas alter.
Continuity mistake: During the scene where Gaby and John are in her bedroom talking, she takes a drag from her cigarette while John asks why she isn't happy, but never exhales the smoke from that drag. 23 seconds pass from that drag to the next one and she's in frame the entire time (it cuts between shots of the two of them together and Gaby's close-ups, but doesn't cut away from her). It's also worth noting that Gaby is never seen smoking again at any other point in the series and no explanation is given as to why.
Continuity mistake: Dr. Cox's hair colour and length change back and forth significantly during the episode.
Seven Minutes to Midnight - S1-E8
Continuity mistake: When Mohinder is back in India, his mother tells him that his sister Shanti died at the age of 5, when Mohinder himself was 2. In "The Hard Part", Mohinder tells Molly Walker that Shanti died before he was born, and shows her a photo of Shanti (who looks 5 years old) and his pregnant mother.
Continuity mistake: Xena leaves Darius' house, where she forgets her chakram. Then there's a shot of her riding Argo, with the chakram attached to her hip. Later Darius shows up to bring the 'missing' chakram to her.
You Are Here - S1-E7
Continuity mistake: Brenda's rape scene scar moves from directly above her left eye to directly above her right.
