It is with heartbreak that executive producers David Milch and Michael Mann together with HBO have decided to cease all future production on the series LUCK.
Safety is always of paramount concern. We maintained the highest safety standards throughout production, higher in fact than any protocols existing in horseracing anywhere with many fewer incidents than occur in racing or than befall horses normally in barns at night or pastures. While we maintained the highest safety standards possible, accidents unfortunately happen and it is impossible to guarantee they won’t in the future. Accordingly, we have reached this difficult decision.
We are immensely proud of this series, the writing, the acting, the filmmaking, the celebration of the culture of horses, and everyone involved in its creation.
Quote from Michael Mann and David Milch: “The two of us loved this series, loved the cast, crew and writers. This has been a tremendous collaboration and one that we plan to continue in the future.”
The release seems to be a reaction to the death of a horse that occurred during the show's second season, chronicled in this LA Times article. Two horses had died during production of the first season.
It's a shame, as I really loved this show, but, of course, safety comes first.
