Continuity mistake: When Gracie is on the phone to Mark and reading Helena's diary, the diary has changed position on Helena's bed before Gracie touches it.
The Greatest American Hero (1) - S1-E1
Continuity mistake: When Ralph is driving his station wagon, the rearview mirror disappears and reappears between the interior and exterior shots.
Continuity mistake: To beat the traffic, Coop skateboards inside a construction pipe. The pipe is on the back of a truck, so it's not exactly very long, and gets picked up by a crane arm mounted on the truckbed itself. However, Coop takes ages to come out of the pipe, and in the shot from inside the pipe it looks as if is dozens of meters above the street level, which isn't. (00:08:00)
Continuity mistake: Sometimes Cyborg is waterproof and sometimes he isn't.
Containment - S1-E5
Continuity mistake: At the end of the episode, when the bad guy is preparing the syringe of small pox, he follows the usual method of tapping out any air in the tube - when he is shown injecting himself, a large air bubble is back in the syringe (which would probably kill him quicker than the smallpox).
Bloodshed in the Bordello - S20-E12
Continuity mistake: Zac goes in a playroom to investigate, puts a truck on a playhouse roof and tries to get a presence to push it off but nothing happens. He walks around to investigate the rest of the room. He squats down to look inside of a tent and when he does the camera pans out to show Billy in the doorway. When it does the truck is not on the roof of the playhouse, but when Zac stands up and walks by the playhouse, the truck comes flying off it.
Two by Two - S1-E6
Continuity mistake: When Alicia presents the slingshot trajectory, Eva says the solar sails will provide "more than enough" power to reach the planet with the U238. Shortly after the sails are deployed, the edge of one of them is damaged, causing the ship to lose enough power to start dropping back to the star. But you can see that about 1/10 of one of the six sails is damaged, or 1.7% of the entire sail array. How is "more than enough" reduced to "not enough" when they lose such a small part of the sails? (00:19:57 - 00:23:33)
Continuity mistake: After the Prisoner Transport Line Major gives the wrong access code, Stanley puts his arm up and rests his hand on the table next to him. But through the rest of their conversation his arm goes from this position to down by his side repeatedly depending on the camera angle. (00:12:25)
Continuity mistake: When Gersham runs from the police in the first scene, his vehicle crashes on a rooftop and hits a wall, bouncing off it, turning and stopping parallel to it. He exits the vehicle, at the point where he crashed, and the vehicle is now positioned differently (turned 90 degrees, pointing straight to the wall). (00:04:20)
Continuity mistake: When the Man in Black wakes up with a noose around his neck, there are only 4 distinct loops in the hangman's knot. A few seconds later, he cuts the rope and collapses to the ground, and there are now 6 distinct loops in the hangman's knot.
Continuity mistake: When Tobler (the male survivor) approaches the Humvee initially, the driver starts noticing his symptoms just as Tobler stops yelling. Later in the film, in flashback, in the same scene, the driver starts reacting a second or two earlier.
Continuity mistake: When Marshall first finds Trip's letter, he holds it from the left side. In the close-up, he's holding it from the right side. (00:02:10)
Lost & Found - S1-E2
Continuity mistake: The way the shower curtain is draped over Todd's shoulder changes throughout the scene when he and Dirk are by the dumpster.
Continuity mistake: After running the roadblock and getting shot in the shoulder, we see Hopper's shirt with a bloody patch about 3" x 2." The camera angle changes and it is now several times larger, positioned differently and oddly-shaped (a bleeding wound would simply expand the stain on the shirt; it would not 'move'). (00:02:55)
Continuity mistake: When Vincent is showing the delivery man his basement to show him the wooden cube isn't there, the delivery man's ID tag is positioned so that the front side is facing outwards. In the next shot, the ID tag has suddenly flipped around. (00:11:20)
Most Likely to Go Your Way (And I'll Go Mine) - S1-E5
Continuity mistake: A group of people are standing before a door with full glass inserts. It has a thought processor for access. Once the group defeats the processor, they open the doors. But the doors are now solid wood, not with a glass insert. (00:29:20)
Continuity mistake: When Dr. Zaius and the gorilla soldiers ride up to the crashed spaceship, his hair is mussed in the long shots and properly groomed and neat in the close ups.
Continuity mistake: The same extras can be seen several times throughout this episode in the chaos scenes in the city and when walking through the country roads to the coast.
Continuity mistake: While Mr. Klimer is forcing Debbie into the car, he for some reason seems to have a Charlie Chaplin-esque moustache which he doesn't have in any other point in the episode.
Continuity mistake: When the girl working in the hospital sees a man from her flash forward, she runs after him carrying several hospital client files. As she runs through the hospital stopping people, the files magically disappear from her arms.
