Crime films focus on the lives of criminals and often glorify criminal acts. They highlight the rise and fall of particular criminals or gangs, showing their secret world through dark nightclubs, piles of cash, and seedy living quarters. Common conventions of the crime genre include gangs, weapons, drugs, violence, hatred, and fast pacing. Some subgenres are cops and robbers, detective/mysteries, film noir, hood films, law and order, and mafia gangster films. The document's author chose the crime genre for their film trailer project because they and their partner enjoy hood films like Top Boy and wanted a genre they felt comfortable portraying in a short trailer.
