Continuity mistake: Series 1, Episode 9: Primal. As Carter and Taggart are crawling through the access tunnel, the torch attached to the side of Taggart's goggles is pointing downwards, below his line of vision as established by the lenses on the front. As the shot changes to a close-up on Taggart, the torch is now pointing forwards, aligned with the lenses. (00:13:50)
Revealing mistake: When we first see the army of Starks outside Global Dynamics, it's quite obvious that only one of them is actually the actor that plays Stark; the others are merely people who look similar.
Invincible - S1-E5
Continuity mistake: The portable physical device that Allison puts on Jack disappears until she takes it off, and she takes off from a different place than where she put it.
Invincible - S1-E5
Factual error: Henry Deacon says people only use 10% of their brain at any one time. That's complete garbage - at times we may use quite a small part of our brains, other times the whole brain lights up with activity. The "10%" myth has absolutely no basis in fact - no-one even seems to know where this figure came from! Given the intelligence of Eureka's residents, Henry (and indeed others in the room) would know this.
Continuity mistake: When they are talking about the power supply Jack has his hands on his hips, except for one shot where they are crossed.
Continuity mistake: When Sheriff Cobb loses his leg, Allison looks down and we see his leg back from the edge of the hole. The camera moves and we see his leg right next to the hole.
Continuity mistake: The amount of water in the pitcher on the table that Callister is sitting at changes a couple of time during the scene.
Continuity mistake: When Callister enters Cafe Diem for the first time he keeps walking as he enters. The camera shot changes and he is now standing near the door then begins to walk further in.
Invincible - S1-E5
Continuity mistake: When Jack jumps over the railing on the bridge his feet are on the concrete, the next shot of his feet they are on the railing, then back to the concrete again.
Continuity mistake: When Jack and Zoe are walking into town, the camera is behind them and there are people walking on the sidewalk towards them. The shot changes to alongside them, then when it cuts back the people have vanished.
Continuity mistake: Henry talks about Eureka installing it's first traffic light but there has always been a traffic light in Eureka.
Suggested correction: The episodes in the first season were aired out of order. The previous episode that showed the traffic light was produced after "Blink."
The light is in every episode including the first one.
Then I would suggest trying to submit a screen shot because I never saw the traffic light on Main and Archimedes in the first episode.
Other mistake: When the parents freak out about Brian being missing, the back of the camper is shown, as is the part of the camper that's missing due to the distortion sphere. But it doesn't make sense; there are some parts of of the camper that shouldn't be there, mainly the one piece above the ground, where the sphere scorched the pavement but left the camper's end right above it completely intact.
