Luck (TV Series 2011) - IMDb
Plot (van Wikipedia):
Luck follows a number of characters who frequent the same horse-racing track.
It stars Dustin Hoffman as "a man in his late 60s just released from four years in prison who's autodidactic, intelligent, and deeply involved in gambling."
David Milch was quoted in Variety as saying; "The pilot is about a bunch of intersecting lives in the world of horse racing...It's a subject which has engaged and some might say has compelled me for 50 years. I find it as complicated and engaging a special world as any I've ever encountered, not only in what happens in the clubhouse and the grandstand, but also on the backside of the track, where the training is done and where they house the horses."
