Some people like to watch the glasses when characters are drinking in movies. The liquid levels tend to go up and down a lot, since the takes are often re-shot or spliced in a different order than was filmed. That's never been one of my distractions, but I do have a tendency to watch smokers a lot. When a character is smoking, I subconsciously keep track of their inhales and exhales. Sometimes a character will take a long draw on a cigarette, but thanks to editing, they never blow it back out. This bothers me, and makes me feel like I'm choking. And I don't even smoke.
Another thing that bothers me is characters who don't go to the bathroom. I know, it's boring to show the mundane part of people's lives. I'm not saying they should show characters in bathrooms more often, that's not my point. I know a lot of this stuff happens off screen and between scenes. But I'm talking about the times when there is no "between scenes".
I'm bothered by the times you specifically know a character didn't have time to go to the bathroom. For example, right now I'm reading Divergent. There's a scene where Tris wakes up and she's running late for a field trip. We know she didn't get up in the middle of the night, because she's so sore from fighting the previous day it would have mentioned how difficult it was to get out of bed. Her friend runs off to get her a muffin, and it takes the entire time she's gone for Tris to change shirts. Then they run off, jump on a train, and so on.
In fact, the book explicitly lays out her every waking moment from around mid day the previous day, until they take the train to the fence. There is no time for her to have gone to the bathroom for nearly 24 hours, and yet - in a first person novel written in the present tense - she never even mentions trying to find time for a bathroom break.
I can't imagine waking up in the morning and not having to use the restroom. It bothers me in stories when they don't mention this normal part of a morning routine. I'm not asking for a detailed description of what transpires on the toilet, but stories where it's obvious they couldn't have gone to the bathroom fill me with anxiety.
I'm also bothered by novels that don't make clear a character's state of undress. I've read several fantasy novels where (this is a made up example) a fighter is woken by a noise and ends up in battle for the rest of the day, and it's unclear whether he ever found time to don that exquisite plate armor the author described when the character was first introduced. Am I supposed to believe he's fighting in a loincloth, or that he sleeps in his plate armor? Because he jumped directly from his bedroll to his horse, and you can't tell me he put his armor on while riding. (He probably didn't go to the bathroom either.)
Divergent again - there's a scene where Tris - who is shy about undressing around others - goes into the bathroom to put on her pants. The pants no longer fit because she's put on muscle, so she puts on a towel when she leaves the restroom. Then she gets assaulted. Her attackers take her towel, and she runs off naked. Maybe. It's implied that she's nude, the attackers even make fun of a birthmark on her rear. But at the same time, I'm surprised she isn't wearing underwear. She wouldn't have been putting on her pants without putting her underwear on first, and there would have been no reason to take her underwear back off before leaving the restroom. Is there no underwear in the Divergent universe? If so, that seems like something the author should have mentioned.
There's a scene in the Doctor Sleep novel that screams "clothing continuity error" to me, but I'd be happy to be proven wrong. I mean, it's Stephen 'effing King, for crissakes, I hate to think he's capable of such a mistake, but we're all human.
But it's the first scene with adult Dan Torrance. He wakes up with a hangover, next to a nude woman who's name he has trouble remembering. He looks down and sees he's nude too. He runs to the bathroom to throw up, grabbing his underwear on the way. He goes through the woman's medicine cabinet, finds three pills he wants to save for later, and he puts them in his pocket. Then he puts on his underwear and goes back to the bedroom. He disentangles his clothes from hers, then puts on his t-shirt and jeans.
In case you missed the problem - he's naked when he puts the pills in his pocket. The only piece of clothing in the room is his underwear, which probably doesn't have pockets.
Anyway, those are the only examples I have at the moment, and I might be misremembering some of them. But this is the kind of thing that stands out to me while I'm reading or watching movies. I'm not obsessive about a lot of things, and I'll accept a lot of unusual fantasy tropes. But bathroom breaks and clothing status are vital to my suspension of disbelief.
