Ashes, Ashes - S1-E6
Continuity mistake: Spoiler! At the end of the episode, after Elektra decapitates Alexandra, the blood pattern on her changes changes when she turns around and asks "any questions?" Most noticeably more blood on her forehead and two streaks down her chin that suddenly appear. (00:49:10)
All-New Halloween Spooktacular! - S1-E6
Continuity mistake: Wanda is spooked by the sight of Pietro transfigured into a corpse. He then asks her if she's okay; Wanda has one hand or both hands in front of her mouth, and they change position between shots too. (00:24:35)
Winning Through Intimidation - S1-E15
Continuity mistake: Panik's Metal Guardian can be seen on the field several minutes before he actually plays it. (00:10:30 - 00:13:00)
Cricket's Place/Volunteer Tilly - S1-E30
Continuity mistake: When Bill opens the bathroom door, it's brown, then green.
Continuity mistake: This show has been widely declared as canonical with the games, by the makers of both this show and the games. The game Fallout 4 establishes the date and time that the bombs drop: Saturday, October 23, 2077, 9:47 AM East Coast Time. Which means it was 6:47 AM West Coast Time. That's a pretty weird time of day to schedule a kids' party with lots of guests and a hired celebrity cowboy.
Suggested correction: They changed a lot of subtle things from canon for the show. Also, all games have got some inconsistencies between them as well. In the show, on the TV, there is a clock that says it's around 9:30 AM the first time we see it and 10:45 when they cut the cake, so it's close to the afternoon and not very early in the morning. The position of the sun confirms this.
So, if it's 10:45 West Coast time, that makes it 1:45 PM East Coast time. Would you carry on a birthday party if the other side of the country got nuked four hours ago?
The show is not taking place on the East Coast; it's on the West Coast in California. The show made it so it was 10:45 AM on the West Coast when the attack began. The attack happened all over the US simultaneously. This is not a mistake but done intentionally. You can call it a deliberate mistake. Definitely nothing wrong in the continuity of the show.
Twilight of the Apprentice - S2-E20
Continuity mistake: Near the end, when Ahsoka runs at Vader, for a split second when he turns around, the part of his mask yet to be sliced off is already missing.
The Crest of Sincerity - S1-E17
Continuity mistake: In the scene where the DigiDestined are running towards a cactus mirage, Patamon is visible instead of Tokomon. (00:03:20)
Continuity mistake: When Scooby and Shaggy are at the "Hotus Dogus" stand in the Coliseum, you can see that Scooby has two flags in his left hand, but after a quick close-up of Scooby, we return to him and his flags have disappeared.
Continuity mistake: When Burke's partners arrive to question Mimsy Grove, she's facing away from them, bending over to untangle her boat's mooring line. But in the very next shot, she's immediately standing up straight and has turned around to face them. (00:38:15)
Continuity mistake: When Whinfrey is at the railway station the weather changes from dry to wet.
Continuity mistake: Multiple times throughout the show, Kimber can be seen in quick shots with light pink hair (the same color as Jem's), when her hair color is actually a dark pink/red color. (02:00:00)
Coach Fussell's Lament - S2-E5
Continuity mistake: Chairface and Chrome Dome arrive at the Brianchild's house in the same car, but drive off in separate cars.
Continuity mistake: Onizuka is on his bike with Mizuki after she utterly murdered the sushi plate. He is still reminiscing about the sweet prime cut tuna while he is at the traffic lights. Several people cross the street; there is a family with a little kid, and a guy in a denim jacket. In the wide shot it's clear that the family is to the guy's left, but in the tighter angle the guy passes them by on the opposite side. (00:34:00)
The Greatest American Hero (1) - S1-E1
Continuity mistake: In one scene, Ralph is in a phone booth desperately trying to make a phone call. Ralph is nervous and panicky. But when you look at his reflection on the phone, you can see a big relaxed smile on him. When it cuts back to him, he is still acting nervous and panicky.
Continuity mistake: "Hostages": During the raid, the bad guys' helicopter lifts off with the hostages aboard. In the next shot, it's still on the ground. Next shot after that, it's airborne again.
Continuity mistake: When Howard sees his ex in the jacuzzi, his glass has a little bit of alcohol in it. When he drops it and it shatters, the glass is empty.
Continuity mistake: The fish that Harley uses to protect herself from the Joker changes shape and size every shot.
Continuity mistake: Kai is flying his dragonfly space craft towards an enemy ship in the beginning with his wingmen as they sing. Kai's shadow is cast on the wall behind him on his left, but when the camera cuts to a close up of him, his shadow is suddenly on the other side. (00:02:05)
The Resurrection of Joe November - S3-E24
Continuity mistake: The confetti and ribbons that fall on the coffin change their configuration with each new camera angle.
Polly Wants a Treasure - S1-E8
Continuity mistake: In the scene where Baloo and Kit walk through the Sea Duck's cargo area to try and find who they think is a stowaway, Baloo lifts a crate of fragile crystal glasses over his head. The crate rotates between shots, judging by its red "Fragile" stamp.
