Best TV mistakes of 2017
Continuity mistake: When Hanna makes the list with names involving her past events, they differ substantially between the close-up when they're written and the final wide angle once the paper is finished. Check Alexander: first an irregular oval with a straight side, then a perfect oval.
Continuity mistake: During the shoot-out near the end, the bullet holes in the pillars Frank and Kyle hide behind change and also disappear at various times. In one shot we see 2 holes when Kyle steps out to shoot, then when he ducks back when fired upon, the 2 holes are gone.
Continuity mistake: When Deborah is talking to Mrs. Chadwick, Mrs. Chadwick's hair keeps changing position and is either covering or not covering her name tag. And when the camera is on Deborah, we still see Mrs. Chadwick's head and she doesn't move it at all.
New this month Continuity mistake: Earlyish in S1:E4 "Growing Suspicion" there is a still photo of Christa Carlyle wearing a cast on her broken right leg. Early in this episode there is a quick motion shot of her handing out a T-shirt to another student. The cast is now on her left leg.
Continuity mistake: Spoiler! At the end of the episode, after Elektra decapitates Alexandra, the blood pattern on her changes changes when she turns around and asks "any questions?" Most noticeably more blood on her forehead and two streaks down her chin that suddenly appear.
New this month Continuity mistake: When Sheldon is putting his mittens on at the table he his seen putting the first one on and the second one is on the table, the shot changes and the mitten is no longer on the table. He raises his hands and both hands have mittens on them.
Audio problem: Right after Carol finishes studying by singing a rap to Katie, Katie congratulates her and Carol hurries out. They exchange several lines of dialogue, but it all appears to be dubbed. During most of the dialogue, each character's mouth is not shown when they speak. However, the cadence of Katie's moving jaw can still be seen from behind, and appears to last longer than the audible speech. Additionally, Katie and Carol can each be heard to speak when it can be glimpsed that their mouths are not moving.
