Factual error: In several different episodes characters are escaping on foot to Canada, as evidenced by Ontario license plates. But the show is set in New England, and the only way to get to Ontario through the Eastern United States is by crossing a major body of water: The St. Lawrence River, Lake Ontario, The Niagara River, or Lake Erie. You can't walk there.
Continuity mistake: The 4 Space Rangers (Carlos, TJ, Cassie, Ashley) morph on the overhanging gangway, then jump off to the ground below. We see them hit the ground, and in the very next shot, they're right next to the Galaxy Rangers, and Andross, who are on the other side of the courtyard. There wasn't enough time for them to move that distance.
Continuity mistake: At the waterfall, after jumping off the cliff and into the water, Skye leads Josh to the rock carvings. Josh's wet hair keeps changing position from being completely slicked back, to partially covering his forehead, to being completely forward over his brow.
Continuity mistake: The back passenger tire blows and they come to a stop, You can see the tire is still inflated. But when they show a close up of the tire its burst at the tread. (00:21:20)
Delenda Est - S3-E11
Revealing mistake: When Dylan and Tyr head to a bridge where supposedly the power source is located as well as Rommie, they start to cross the bridge. As the camera is facing Dylan and Tyr, the next scene two aliens teleport in. Rewind the video to facing Dylan and Tyr and play in slow motion. Watch the bottom portion of the screen and notice the top portion of one of the alien's head go into the camera as if the aliens walked into position for the teleportation.
Continuity mistake: "Railway Station" (Adventure 2, Part 4): Steel's crooked bow tie straightens itself out between takes as he's confronting the soldier's ghost. (00:04:00)
Give Me Your Princess - S1-E17
Continuity mistake: Commander Keith pilots the blue lion for part of this episode since the princess is trying to learn to fly the black lion. When Keith is transported to the lion it is the black lion.
Galactica Discovers Earth: Part 1 - S1-E1
Revealing mistake: When Troy and Dillon land on Earth, they take their bikes onto the freeway. They're followed by a large group of curious bikers. When two of the bikers move alongside Troy and Dillon and start talking to them, it's obvious that all four bikes are now mounted on a trailer, instead of riding on the road. Easiest way to tell is that their heads are higher up than the other bikers and the front wheel isn't turning.
Continuity mistake: When Stephanie runs in and sees 'Jim' on the floor there is a huge puddle of blood on the floor. When 'Jim' changes back into Amelia the puddle disappears.
Earthbound - S1-E17
Audio problem: McCauley and the engineer take a space walk to repair the ship's engines. We hear their tools clanking against the metal hull as the repair is made, and they pound loudly on the hatch door to reboard the ship when they've finished. None of these sounds would be audible in the vacuum of space.
Other mistake: The Lakota is attacking a small group of white men. One is face down on the ground, and he lifts his head to cut his throat. In the background are two cowboy actors joking and twirling their guns. One drops their gun and picks it back up. (00:20:43)
Continuity mistake: Elisabeth Shue is talking to Homelander by her car. As she gets her baby out of the car, she says "can we please just talk later" and has a muslin hanging over her right shoulder, turns around, and from the reverse angle the muslin is bundled up in front of her, not over her shoulder at all. Then the angle changes again and it's back where it was before.
Remembrance - S1-E1
Character mistake: Picard and Data are playing poker at the beginning of the episode. Before the actual faces of the players are revealed, we are shown close-ups of their hands as they put down the chips for the bet. When Picard says his first line in the series it's "See", and it is literally true, because in the previous shot, Data put his 5 cards down on the table and face up. (00:00:50)
Factual error: The bad guy tells the townsfolk to 'Get out of Dodge.' Not a saying used in 1879, despite Dodge City being a real place. In fact by this time Dodge City was no more violent than many other places, so it wouldn't have been used as a direct comparison either. There's no record of this specific phrase being used until Gunsmoke, in 1955.
Continuity mistake: At the end of the battle between Jaden Yuki and Gravekeeper's Chief, just as the explosion settles, in one shot you see the Gravekeeper's Spear card to the left of Gravekeeper's Chief on the duel disk. However in the next shot Gravekeeper's Spear is replaced with Magician of Black Chaos, which Chief neither has in his deck or ever played in the match. (00:13:35)
Power Broker - S1-E3
Factual error: Every guard in the prison has the emblems of Hamburg on his/her shoulders of the uniforms. Zemo is said to be imprisoned in Berlin, so they are wearing the wrong emblems.
The Tale of the Pinball Wizard - S1-E13
Visible crew/equipment: When Russ is in the royal chair and it is moving on its own, right after it hits the witch you can see a crewman behind the chair pushing it.
Monkey Fun - S2-E13
Other mistake: Season 2 episode 13 "Monkey Fun": Just before the enlarged Titano appears at the zoo, there is a family watching normal-sized monkeys in a cage. The family father (farthest on the right) has a drawing disorder with his eyes: their pupils look up and down, respectively, giving him a rather goofy expression.
The Mind of Simon Foster - S3-E23
Continuity mistake: When the pawnbroker closes his metal gate, he's facing the wire mesh. When the shot cuts, he's instantly facing away from it. (00:10:15)
Emergency Marineville - S1-E11
Continuity mistake: When the second group of Spearhead jets take off from Marineville there are only two jets, but in the next shot you can see three jets, and in the next shot there are two again.
