Gangster crime films typically follow a narrative pattern. The protagonist is often an immigrant of Italian descent who strives to attain the American Dream but whose fall is usually due to his own greed or stupidity. The settings are usually run-down urban areas that provide a view of the secret criminal world. Key themes include rivalry, morality, betrayal, ambition, materialism, self-destruction, loyalty, and the difference between appearances and reality. The target audience for gangster crime films is typically male adults between 20-50 years old.
