Often in films or TV a character will take an annoyingly long time to answer the door or phone, but the ringer or knocker willl always wait. This is not how real life is.
Not everyone uses Sprint 
It happens in one of the Olsen twins movies.
Misspeak and then correct oneself. I do that several times every day. Seems like a character in a movie could do it once in a century.
In Bullit, Steve McQueen picks up an armload of TV Dinners at the market.
My peeve:
Discharging firearms in enclosed spaces has absolutely no effect on hearing. You can fire 6 rounds out of a .357 in a phone booth and still hear an ant fart at 500 paces.
I’m not sure if this happens in movies, but I notice in real life that when people talk, a heck of a lot of what they begin to say is aborted in favour of something better.
A typical example would be “It might, Well it could er, I think it’s going to go the way jo said it would go. I am… I think we should do it the other way”
Maybe not a good example, but I think you know what I mean. More often than not people in real life don’t speak perfect sentences like people in films do.
With the exception of those intelligent few who construct their dialogue internally before releasing it into the world. I like to think I am one of them. But then again I like to think I am irresistable to women, and the future emperor of earth.
This is a good one. I’ve fired blanks (the original kind. I don’t fire blanks in the sexual way so stop laughing) and lost hearing temporarily for a good many seconds.
click BANG. muffle muffle. WHAT!. Shouted muffle muffle. I CAN’T HEAR YOU!!
I don’t know why so many people complain about characters not saying “Bye” when they hang up the phone. The phone doesn’t need to hear “bye” in order to end the communication. There’s not some magic listening device that will get all cranky and complain if it doesn’t hear the word “bye”.
Frankly, I never end my phone calls with “bye”. I’m not a Pavlovian-trained animal that needs an exact, precise cue to know when a conversation is over.
In my opinion it’s simple courtesy. In my job I speak to Americans on the phone a lot. My final word is ‘bye’ and when they return the ‘bye’ it seems as if they didn’t expect to say it and are trying to comply with an englishman’s custom.
Most of the time they are pleasant to talk to.
People never just mess up their words and say something funny. I’m not sure I can describe it much better than that. Seinfeld, for example, almost did this, but that’s a TV show.
This depends. If your adrenaline is pumping and you’re in a life-or-death situation, you may not even hear the gun going off. I know that, when stalking game (I dislike using blinds) I have sometimes not worn earplugs to better hear the noises of the deer or hog. When I saw one run out in front of me and took my shot, I didn’t even notice the report of the rifle, much less have it hurt my ears.
In films, labor and delivery takes about 15 minutes. Women go from walking down the street, la, la, la, la, la, BAM, groan, moan, shriek, oops, there’s a baby.
I suppose it has something to do with familiarity. I rarely talk with people I’m not significantly comfortable with (hell, some might call us “friends”, but those people are fools 
), so it’s rarely inappropriate for me to finish a phone call by telling my buddy, “Fuck off, you sack of nefarious glop”, and they’ll return with “In a pig’s eye, you dastardly Republican fascist!” click
Identity.
Goldie Hawn did… she made it sort of a sexy signature, in a girlie-cute kind of way.
Check out River Phoenix in My Own Private Idaho.
In movies, you never see people in courtroom scenes do any of the things people do in real courtrooms… which in real life is dull, dull, dull!
I already said that I’m talking about movies where the person hasn’t been near a shower for days. Survival movies. I was talking about movies where someone has not had a shower in quite some time. Not that day.
And nobody wants to see people actually having their periods in movies. But I do think I would like it better if it were acknowledged that such a thing exists in the universe.
Actually in Miss Congeniality II Gracie pretends to get cramps so she can escape from her FBI escorts. But she was faking it.
Whenever they do, the thing that came out first is some huge, humiliating freudian slip.
A related one: when there is some sort of recording and the character rewinds to hear something again, it always starts replaying exactly where they want it.
Because they have good taste.
Seriously, if you were a set designer and you wanted to establish your leading man as a young, successful, technologically savvy genius, what are you going to have him use – a sleek, sexy, bleeding-edge piece of Apple gear, or a generic black lump of plastic from Dell or Compaq?
Why? They’re using Macs.
On the subject of mestruating, I do recall that it was a plot point in one of the Friday the 13th movies that the heroine doesn’t have sex because of her period, thus insuring her survival (i.e. Jason never kills the girl who hasn’t had onscreen sex).
Neither. I’d have him using a box he built himself.
