In movies, especially, whenever anyone comes home from grocery shopping they're always carrying a paper bag with a loaf of French Bread sticking out of it.
Almost no one goes to the bathroom. Occasionally they do for comedic or shock value, but it's not a normal everyday thing like it is for everybody else. One exception was Pulp Fiction, where John Travolta's visits to the toilet seemed to be part of the story. But as a rule, movie people are a non-excremental species.
In movies people can take all kinds of falls without getting hurt. I've got some news - skidding on concrete hurts.
Ever watch 24? The whole series is supposed to be about a 24 hr period. But no one seemed to get tired, hungry, or have the above mentioned need to go to the bathroom.
In most movies no one ever just stops or starts a car. They burn rubber, slam on breaks, you can't start or stop in a movie without squealing tires.
-- an aside. I watched a lot of The Soprano's and I noticed that whenever Christopher showed up at your door unannounced, nothing good was going to happen to you. Didnt matter if he was smiling.
In the movies a person can be gravely wounded and shake it off, but as soon as someone tries to bandage the wound, it suddenly hurts.
The movie world is a very violent place, and no one seems to run out of ammunition, no matter how much they shoot without reloading.
