PETA is coming after Luck after two horses were euthanized during production, the organization announced last week, and now HBO has responded. According to PETA, HBO hasn't taken appropriate precautionary measures to ensure the health and safety of the horses; according to HBO, after the second horse died, the production implemented new protocols, including "the hiring of an additional veterinarian and radiography of the legs of all horses." (The American Humane Association has a full rundown of all its on-set precautions, and it's weirdly fascinating: "Actors carried treats in their pockets and the goat and dog paid active attention to this detail." We bet!) Most of the episodes of Luck carry the AHA's "no animals were harmed" stamp, but the pilot and the seventh episode do not, because, yikes, two animals were harmed enough that they had to be put down.
