Continuity mistake: Miguel kicks and breaks a staircase railing during the school brawl. For a second it cuts to Robby. When it cuts back to Miguel, the railing is fixed.
Revealing mistake: When Johnny shows up to Cobra Kai dojo and all the kids are there. In the video playback they show on the phone you can see Miguel didn't land the kick, and the kid just fell down. (00:28:18)
Other mistake: Hawk gets a mohawk, but his hair was too short to style it like that.
Suggested correction: The mohawk was not a prop, but the actual hair of the actor they shaved off and mended together for him.
That is true, it was the actor's actual hair, but in the realm of the show, Eli's hair was not long enough to style that large of a mohawk out of it.
Continuity mistake: Johnny's car gets hit, and he comes up and starts banging on the windows. When the girls drive off, the rear window is down, when it wasn't prior.
December 19 - S3-E10
Revealing mistake: While Kreese is fighting Johnny, the stunt double is clear in several shots.
Revealing mistake: When Sam and Tory confront each other at school, the same extra (a girl wearing glasses) appears in two different places. She is behind Sam during the confrontation but Robby also runs past her in another shot.
Continuity mistake: When Johnny leaves his home to go to Daniel's place it's night time but when he gets there suddenly it's daytime.
Suggested correction: Daniel lives far away. Johnny must have driven all night.
That implies that Daniel lives like 5-6 hours from his job.
I actually assumed that it was already like 6am or something like that and knowing how sprawled our everything is there figured maybe it was like a 40 min drive. But then Daniel's wife also says it's Saturday morning yet Miguel and Sam are in school.
Continuity mistake: When Sam and Tory are at the party, they both get two shots of vodka in the purple cup. Tory drinks the vodka, but after a while the vodka reappears.
Continuity mistake: When in the woods at the meeting spot before the flag events, the sun is first high up in the sky, then very low in the background close to setting, then back high up in its original position (all from the same exact spot in each scene).
Continuity mistake: When Daniel is fighting Robbie's former friends on the beach, you can see a ship in the ocean behind him. The camera then cuts to his opponent, and then back to Daniel and the ship is gone.
Other mistake: As Sam recovers from her injuries, she keeps babying her right arm, when it was her left that Tory scraped with the wrist chain and bandaged.
Suggested correction: It was her right arm that Tory cut.
Match Point - S4-E5
Continuity mistake: Kreese and Silver have 2 glasses of water on their table. In the next shot, a waiter comes and places those glasses of water on the table. (00:17:57)
Continuity mistake: About 8 minutes into the episode, Silver is talking to the other female sensei, and she sees the stretch limo crash through the gates on her tablet. It makes it all the way through but when she picks it up to show Silver, the video backs itself up.
Continuity mistake: Sam is barefoot while reading her book on the lounge chair, but she has flip-flops on a few minutes later.
Suggested correction: It's not uncommon for people wearing sandals to slip them on and off, wasn't she getting ready to leave anyway at that point?
No, this was before she decided to leave, she was just sitting in the chair still reading.
Continuity mistake: Lawrence is giving a ride to a guy who is on the phone. There is an older vehicle behind them. The older vehicle moves closer when the scene changes. The entire time, we can see out the back window.
King Cobra - S3-E6
Continuity mistake: When Miguel realises Johnny liked all Ali's photos, he looks embarrassed and shakes his head to the right, with his mouth open. In the next frame he looks significantly different, with his mouth shut. (00:09:23)
Revealing mistake: When Silver cuts open the box of new equipment, the razor knife has no blade. (00:05:53)
Other mistake: Johnny is browsing Facebook and accepts a friend request for his childhood crush and checks out her profile. The Facebook post on Ali Mille Schwarber's profile with a photo of her smiling has a lock icon next to the date. This indicates that the photo/post is private and no-one should be able to see it except for Ali. (00:36:58)
Other mistake: When Miguel and his friends use the restroom, he zips up after using the urinal, but there is no zipper on his costume when he turns around.
December 19 - S3-E10
Continuity mistake: After Johnny picks up the small spear in the dojo, the first spear (next to the one picked up) changes angles (tilting positions) every time it's shown during the scene.
