A character who is highly intelligent, has cultured and refined tastes, and speaks with an English accent is a sociopath who kills innocent men, women and children with no sign of remorse.
Death from projectile weapons, strangulation, drowning, asphyxiation, or stabbing is virtually instantaneous, unless the character is a) the hero, b) the villain, c) the villain’s unstoppable bodyguard, or d) some incidental character who must live on to save the hero’s life by a well-placed gunshot or by providing critical information.
Any blow to the head with a blunt object produces instant unconsciousness. The victim sinks slowly to the floor without even uttering “ouch”.
Nobody ever has to use the restroom. Those who claim to have to go are obviously trying to escape from detectives/mafiosi/sinister agents by climbing through the back window into the alleyway.
Christianity is no longer a force against evil – more often than not, it IS the evil. Those who espouse religious beliefs are either small-minded bigots or neo-Nazi terrorists. Every bishop in the Catholic Church is corrupt and abuses his congregation financially and/or sexually. The only ones who quest against Satan are neo-pagans (even though AFAIK they don’t even believe in Satan) or weary agnostic detectives.
A teenage girl being seduced by a grown man is a victim of a sick serial pedophile. A teenage boy being seduced by a grown woman is part of a sensitive coming-of-age story.
Opposing Correlary: sexual pairings between an older man and a much younger woman are used to highten the drama or provide a romantic flair; sexual pairings between an older woman and a much younger man are used strictly for comic relief, especially of the gross-out variety.
There are no single fathers – at least, none worth showing in a positive light.
Overweight people are either obnoxious jerks, feeble cowards, or objects of ridicule / disgust. Any film that claims to have a positive message about size must still indulge in plenty of fat-people-are-disgusting jokes.
Bystanders are never injured during high-speed car chases. They always manage to leap out of the way just in time. All except the lady with the baby carriage, of course, who will stand there like a deer in the lights or try to shield the carriage with her body instead of just pushing the thing out of the way. Of course, she will be saved by some amazing bit of luck anyway.
