Movie passengers either don't pay cabs at all, or have the exact change. Same is true in restaurants. Checks are always designed to be 15 percent under the bills the male costumer has in his hands first.
Movie people can get cabs instantly, unless they are in danger, whereupon no cab can be found
CHASES
Woman falls to the ground whilst being chased by a bad guy, even when running over level, unobstructed terrain. Note that when a man and woman are being chased, usually the woman falls, then the man pauses and helps her up.
Corollaries to the above:
o Man will then continue to run with woman, holding her by the hand or preferably upper arm, even though this takes them both below the speed either one could make on their own.
o All movie women must be pulled along by their hands, even if the male puller is short & fat and the woman is a track star.
o All movie women try to run in heels, never stopping to kick them off.
Women not only have to be pulled along, they do not have enough sense to run and keep running unless a man touches her elbow, holds her hand or puts his arm around her shoulders.
Chasees will always stop to throw obstacles (trash cans, lumber, chairs) in their pursuers' way. No matter that they take three times as long to dump the obstacles as it takes the chasers to simply jump over them.
CHESS
Good Chess players are always portrayed as upper class. (Go to any tournament and see how many rich guys there are there. NONE! They're too busy chasing women and driving fast cars to play chess.)
Chess players in movies are always all around brilliant and charming people.
Great Chess players are always honored to play on some rich guy's fancy Philipino Art Set. (In reality, better players are almost always adament about playing on a plain, unadorned wood or plastic "Staunton" set. No red or blue pieces, no ceramic or metal, no elephants for rooks.)
Supposedly brilliant players usually miss one move checkmates in critical games. This is akin to a professional race car driver backing his station wagon into the garage door.
On the other hand, good players are often portrayed as seeing 15 or 20 moves ahead in detail from a middle game, when there are still many pieces on the board. (One could more easily predict the next president and all 535 congressmen correctly before the election.)
Beginners usually beat experienced players, as a mechanism for showing the neophyte's native brilliance. (This is about as common as a tall, athletic man who's never seen a basketball beating an NBA player in one-on-one.)
Players who have lost more pieces than their opponent come up with brilliant ways to win anyway.
CLOTHING
Male characters generally are cold-natured. They need to wear jeans and leather jackets when the female characters are comfortable in cutoffs and a halter top.
Heroes are the exception to the above. He often is more comfortable in extreme cold after losing his coat or having the shirt ripped from his back. When this is not true (Cliffhanger), swimming in ice water helps.
Whenever anyone knocks out anyone else and takes their clothes, it's always a flawless fit.
COMPUTERS & ELECTRONICS
Word processors never display a cursor.
You never have to use the space-bar when typing long sentences.
Movie character never make typing mistakes.
All monitors display inch-high letters.
High-tech computers, such as those used by NASA, the CIA, or some such governmental institution, will have easy to understand graphical interfaces.
Those that don't, have incredibly powerful text-based command shells that can correctly understand and execute commands typed in plain english.
Corollary: you can gain access to any information you want by simply typing "ACCESS ALL OF THE SECRET FILES" on any keyboard .
Likewise, you can infect a computer with a destructive virus by simply typing "UPLOAD VIRUS".
All computers are connected. You can access the information on the villain's desktop computer, even if it's turned off.
Powerful computers beep whenever you press a key or whenever the screen changes. Some computers also slow down the output on the screen so that it doesn't go faster than you can read. The really advanced ones also emulate the sound of a dot-matrix printer.
All computer panels have thousands of volts and flash pots just underneath the surface. Malfunctions are indicated by a bright flash, a puff of smoke, a shower of sparks, and an explosion that forces you backwards.
People typing away on a computer will turn it off without saving the data.
A hacker can get into the most sensitive computer in the world before intermission and guess the secret password in two tries.
Any PERMISSION DENIED has an OVERRIDE function (see "Demolition Man" and countless others).
Complex calculations and loading of huge amounts of data will be accomplished in under three seconds. Movie modems usually appear to transmit data at the speed of one terrabyte per second.
When the power plant/missile site/whatever overheats, all the control panels will explode, as will the entire building.
If you display a file on the screen and someone deletes the file, it also disappears from the screen (e.g Clear and Present Danger).
If a disk has got encrypted files, you are automagically asked for a password when you try to access it.
No matter what kind of computer disk it is, it'll be readable by any system you put it into. All application software is usable by all computer platforms.
The more high-tech the equipment, the more buttons it has (Aliens). However, everyone must have been highly trained, because the buttons aren't labelled.
Most computers, no matter how small, have reality-defying three-dimensional, active animation, photo-realistic graphics capability.
Laptops, for some strange reason, always seem to have amazing real-time video phone capabilities and the performance of a CRAY Supercomputer.
Whenever a character looks at a VDU, the image is so bright that it projects itself onto his/her face (see "Alien", "2001", "Hackers").
CONVERSATIONS
Two people will often converse while one stares out the window, with their back to the other. When an emotional point is made, the first person will turn around.
CRIME
When you go to rob a bank in a film, you will always choose the teller who has just started his or her first day on the job.
