For a marathon to work, you need a few films that people already love, at least one genuine discovery, and something that sparks a conversation at the end.
Crime cinema at its best is a mirror - not a celebration of lawbreaking, but an examination of what drives people to it.
Suffering from insomnia, disturbed loner Travis Bickle takes a job as a New York City cabbie, haunting the streets nightly, growing increasingly detached from reality as he dreams of cleaning up the filthy city.

A bullied teenage girl forms an unlikely friendship with a mysterious young man who protects her from her assailants, while she copes with the pressures of her final examinations.
A botched robbery indicates a police informant, and the pressure mounts in the aftermath at a warehouse. Crime begets violence as the survivors -- veteran Mr. White, newcomer Mr. Orange, psychopathic parolee Mr. Blonde, bickering weasel Mr. Pink and Nice Guy Eddie -- unravel.
Keller Dover is facing every parent's worst nightmare. His six-year-old daughter, Anna, is missing, together with her young friend, Joy, and as minutes turn to hours, panic sets in. The only lead is a dilapidated RV that had earlier been parked on their street.
These films don't romanticise crime - they examine it. The best of them leave you uncertain about who you were rooting for.
A card shark and his unwillingly-enlisted friends need to make a lot of cash quick after losing a sketchy poker match. To do this they decide to pull a heist on a small-time gang who happen to be operating out of the flat next door.

Best friends Peppe and Mario are thieves, but they're not very good at it. Still, Peppe thinks that he's finally devised a master heist that will make them rich. With the help of some fellow criminals, he plans to dig a tunnel from a rented apartment to the pawnshop next door, where they can rob the safe. But his plan is far from foolproof, and the fact that no one in the group has any experience digging tunnels proves to be the least of their problems.
Raised in a poverty-stricken slum, a 16-year-old girl named Starr now attends a suburban prep school. After she witnesses a police officer shoot her unarmed best friend, she's torn between her two very different worlds as she tries to speak her truth.
In Prohibition-era Chicago, musicians Joe and Jerry witness a mob hit, and flee the state in an all-female band disguised as Josephine and Daphne, but further complications set in.
The best hopeful films aren't naive. They acknowledge the difficulty and find the humanity anyway. These do that.
Great crime cinema lingers because it doesn't offer easy resolution. The moral weight sits with you.
