2017 film directed by Paul Schrader

John LeTour is a recovering drug user who suffers insomnia and still deals to a high-end New York clientele, even though he’s trying to move on from the business. John’s professional midlife crisis becomes something more acute — and dangerous — when he re-encounters an old flame while a string of seemingly drug-related murders rocks the city.

A mentally unstable Vietnam War veteran works as a night-time taxi driver in New York City where the perceived decadence and sleaze feed his urge for violent action.

The life of boxer Jake LaMotta, whose violence and temper that led him to the top in the ring destroyed his life outside of it.
