The show starred Dustin Hoffman, so it should have been a hit, right? One of the biggest names in Hollywood didn’t manage to make this show a hit, so what went wrong? Well, the show first aired in January 2012, and despite getting renewed for a second series, we never got to see it because, by the half of March 2012, it got canceled.
Since the show centers around horse betting, it’s animal safety concerns that actually got it canceled. That’s because several horses were injured and were later euthanized during filming. HBO said it wanted to make sure such accidents won’t happen again on its sets and decided to cut it short.
