Unlucky: Three Horse Deaths in HBO Drama 'Luck' Suspends Filming

LOS ANGELES (The Blaze/AP) — The goal of the HBO racetrack drama "Luck", according to the series' website, was to take a "provocative look at the world of horse racing." Filming of the series has been provocative to say the least with three horse deaths connected with the show and now an indefinite suspension of filming while an investigation is underway.

As recently as Tuesday, a horse used in the show was injured and euthanized. The humane group that oversees Hollywood productions has issued an immediate demand "that all production involving horses shut down."

"We are also insisting that this stoppage remain in full effect pending a complete, thorough, and comprehensive investigation," the American Humane Association said in a statement. It noted that the accident didn't occur during filming or racing.

The animal was being led to a Santa Anita Park racetrack stable by a groom when it reared and fell back Tuesday morning, suffering a head injury, according to HBO. The horse was euthanized at the track in suburban Arcadia, where "Luck" is filming its second season.

In the series, which was created by David Milch ("Deadwood," ''NYPD Blue") and looks at racing's seedier side, Dustin Hoffman plays a crime kingpin who's scheming to gain control of a racetrack and introduce casino gambling.

Watch this recap of the drama thus far:

During season-one filming in 2010 and 2011, two horses were hurt during racing scenes and euthanized. HBO defended its treatment of the animals, saying it's worked with the American Humane Association and racing industry experts to implement safety protocols that exceed film and TV industry standards.

The American Humane Association's film and TV unit, the group sanctioned and supported by the entertainment industry to protect animals used in filming, called for a production halt at the Santa Anita Racetrack in suburban Arcadia after the second horse's death.

Racing resumed after new protocols were put in place and proved effective, Karen Rosa, the AHA unit's senior vice president, said in February.

On Tuesday, Dr. Gary Beck, a California Horse Racing Board veterinarian, said he had just examined the horse as part of routine health and safety procedures before it was to race later in the day. The horse passed the inspection, the AHA said.

"The horse was on her way back to the stall when she reared, flipped over backwards, and struck her head on the ground," Beck said in a statement. An attending veterinarian determined that euthanasia was appropriate, he said.

Dr. Rick Arthur, medical director of the state racing board, said such injuries occur in stable areas every year and are more common than thought. A necropsy will be conducted, he said, which is routine with all fatalities at racing board enclosures.

An American Humane Association safety representative was at the track when the accident occurred and "as always, all safety precautions were in place," HBO said in its statement that said it was "deeply saddened" by the horse's death and was working with the AHA on its inquiry.

The first two horse deaths drew criticism from People for the Ethical Treatment of Animals, which said that safety guidelines used in filming failed to prevent the deaths "so clearly they were inadequate."

Kathy Guillermo, a PETA vice president, said at the time the group didn't consider the matter closed.

"Racing itself is dangerous enough. This is a fictional representation of something and horses are still dying, and that to me is outrageous," she said.

On Tuesday, Guillermo said PETA sent complaints about "Luck" to Arcadia police and an animal humane society in nearby Pasadena.

"Three horses have now died and all the evidence we have gathered points to sloppy oversight, the use of unfit, injured horses, and disregard for the treatment of thoroughbreds," Guillermo said, calling for an immediate halt to filming.
