Mean Streets

1973 drama co-written and directed by Martin Scorsese stars Harvey Keitel, Robert De Niro.

Keitel plays a young man in New York's Little Italy who makes a living doing collections for his wiseguy uncle. When offered a restaurant to run for his uncle he is forced to choose between what might be a lucrative future or love and friendship.

His girlfriend is has epilepsy and his best friend, Johnny Boy, is a loose cannon. These relationships create tension between he and his uncle.

The young cast (then) shines in what is basically the story of a young man's conflicts between his real life and his moral dilemmas...all played out on the "Mean Streets".

Fascinating and riveting. De Niro is incredible (What's a mook?)
