The Buffer - S1-E3
Continuity mistake: When Mickey touches Trish's boob, her hand is over the grey shirt, in the next shot, her hand in inside the grey shirt, and over the grey shirt again in the next shot.
Episode #1.3 - S1-E3
Audio problem: Elaine refers to someone's "ChatsApp" account, but her lip movements show she is actually saying "WhatsApp." (00:13:55)
Visible crew/equipment: When Adrian is getting something from the snack machine, the cameraman can be seen in the snack machine's reflection. (00:26:30)
Factual error: The provincial police is always described as the Ontario Police Department (OPD) instead of the correct Ontario Provincial Police (OPP).
Factual error: Johann Eck is dressed as a cardinal and Albrecht von Brandenburg addresses him as "Your Eminence" and kisses his ring. In reality, Eck was not a cardinal. Albrecht, however, was. It should be Eck showing deference to him, not vice versa. Albrecht was also only thirty, half the age of the actor playing him.
Other mistake: The kids are viewing the VHS tape...but somehow the tape ends up in the old Hispanic woman's house...who then shoots it.
Continuity mistake: When Josh is asking his dad if the cops were hot, from the side he's leaning forwards with both elbows on his knees, then from the front he's more upright with one hand on his knee, arm bent out to the side. (00:09:45)
Continuity mistake: The way "Jack Griffin" is written on the board changes in various shots.
Factual error: Every Time the Shadow Raiders deploy to Somalia, they use a Blackhawk nicknamed "Adele" for their missions. I can understand the helos being transported via fixed-wing aircraft, but on their last mission they leave Georgia, and reach Somalia the same day, flying in the Blackhawks. It would take them some 15-20 hours not including fuel stops. Yet the mission is completed in the time it takes to find a bomb in downtown Atlanta.
Boundaries - S4-E3
Continuity mistake: Alex and his mom are talking with Grandma about masturbation. Alex is in his school uniform shirt but for one shot he has a hoodie on, then in the next shot it's gone.
Episode #1.2 - S1-E2
Factual error: The catalogue of errors made by the SAS team (e.g. being caught out in the open, not posting a watch, not using cover) would be unlikely to be made by an ordinary trained infantryman, let alone an elite special forces unit.
Other mistake: Just before Rey jams her staff into the worm's mouth, she moves her arms to line it up. In a single frame, her left hand goes from holding the top of the staff underhanded to overhanded with no adjusting it. (00:01:06)
