Continuity mistake: When Will Parry visits his grandparents, the grandmother is sitting on the sofa next to Will's grandfather. The grandmother's position keeps changing from sitting right next to him to being further apart.
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)
Revealing mistake: The ghosts often cast shadows.
Suggested correction: You can also hear their footsteps. But I'm not sure this is a mistake, just their own perception. Within the ghostly world they appear and act just like they would in life.
The ghosts are manifestations of energy, therefore they have no physical body to block light. Even if in the ghostly world, physics are physics and there should be no shadows.
Chaos Is the New Cocaine - S1-E3
Continuity mistake: Alex opens a bottle of wine. She takes the cork off the corkscrew with both hands and the bottle of wine spins from not showing the label to showing it. (00:37:55)
Chapter Four: Housechilling Party - S1-E4
Revealing mistake: When Ryan's iPhone vibrates with a text message from his mom, the text message is timed 5 hours before the time on the lock screen. An immediate message would normally indicate the time received as "now." (00:06:45)
Picture's Up - S1-E5
Continuity mistake: When the detective goes to retrieve the water bottle that Zach discards into the recycle bin, he picks it up with a napkin by the top. In the next shot, he is placing the bottle in a plastic bag top first, holding the bottle with the napkin by the bottom. (00:42:00)
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)
Continuity mistake: The mayor Bobby and Keri are talking in a restaurant. Flashback 5 years - the same man sits at two different tables in two different sequences. (00:13:35)
Revealing mistake: The main character gets into a short wrestling match on the landing of a star well. The bad guy fires a shot over the main character's shoulder, which should have hit the wall he was leaning against, but no damage is shown on the wall. (00:05:40)
Factual error: Almost none of the senior police officers wear the correct medal ribbons. Brian Moore and Pat Geenty wear the Order of the British Empire, which neither had. Geenty wears the General Service Medal, for military service in Northern Ireland, although he was never in the armed forces. Moore does not wear the Queen's Police Medal, which he was awarded in 2009. Both wear the Diamond Jubilee Medal in 2011, although it was not awarded until 2012. Andy Parker wears an unidentified ribbon (possibly intended to be the Queen's Police Medal, which he was awarded in 2010, but looking nothing like it) and the Golden Jubilee Medal, but does not wear the Diamond Jubilee Medal or the Police Long Service and Good Conduct Medal to which he was also entitled. Mike Veale and Ray Hayward wear no medal ribbons at all, although both would be entitled to the Golden Jubilee Medal and Police Long Service and Good Conduct Medal (and Veale also to the Diamond Jubilee Medal after 2012).
Deliberate mistake: In the restaurant after their daughter finishes talking to Niko, Erik turns the tablet device around and sets it on the table to talk to Niko. From his perspective, he is looking down at the screen. But in the other shots from Niko's perspective, where he is a life sized hologram, his figure is shown looking up and meeting her eyes. But from her perspective it should look like he's looking down at the table.
Continuity mistake: Detective Hoffman is in Grey's bar when Grey serves him a drink with a cherry on a skewer. The cherry alternates between being down in the drink or up leaning on the rim of the glass.
Other mistake: The Zeds infect others through directly touching them. This rule extends to touching their clothes and backpacks, which makes no sense.
Other mistake: The extent to which the classmates wrapped Miles in cellophane with his hands folded in front of his groin would make it difficult, if not impossible, for Miles to get out of the lake alive on his own. Miles did not drown... or suffer any injuries.
Continuity mistake: The Empire State Building is shown in white lights at 14.56 and 17.11 into the episode. The same night at 17.13, it is red, white, and blue.
