PETA is calling on HBO and “Westworld” to stop using real-life elephants in future productions, claiming that one of the elephants used in the most recent episode was the victim of abuse. But HBO has pushed back, saying in a statement that all animals were “treated with the utmost care and respect for their health, safety and well-being.”

“All of the animals featured on HBO series are treated with the utmost care and respect for their health, safety and well-being. A certified animal safety representative from American Humane was present at all times during any animal action on the set of WESTWORLD,” HBO said in a statement provided to TheWrap. “The AHA has confirmed that the animals were well-treated, and the production received the designation of “No Animals Were Harmed.” We are reviewing the circumstances related to archival training footage which included one of the elephants that appeared in the series. Of course, none of this video was shot during the production and does not in any way reflect practices on our sets.”

The statement came in response to a letter from PETA addressed to the premium cable network’s programming boss, Casey Bloys, earlier Monday following the third episode of Season 2, “Virtu e Fortuna,” which began with cold-open that revealed a new park for the series based on British-occupied India, “The Raj.” There guests can ride elephants and go on safaris to hunt Bengal tigers. PETA says it identified one of these elephants as Tai, an animal who suffered abuse during training by the outfit Have Trunk Will Travel.

“I’m writing to you today on behalf of PETA and our more than 6.5 million members and supporters worldwide with concerns over the use of live animals on ‘Westworld’–especially wild animals, such as the elephants who appeared in last night’s episode,” Lauren Thomasson, PETA’s Manager of Animals in Film & Television wrote. “In light of the egregious cruelty and human health risks as well as the public’s growing opposition to the use of animals for entertainment–and because reports say that there are still plans to use bears this season–we’re urging HBO to commit to not using any wild animals in future episodes or other series.”

“Considering the realistic and cruelty-free CGI technology that exists today, all wild animals in HBO series should be computer-generated, just the way the tiger was so beautifully done in last night’s episode,” Thomasson added. “May we please hear from you right away to confirm that any plans to use live bears or other wild animals will be canceled and that you will pledge to stop using and exploiting wild animals?”

Dear Mr. Bloys, I’m writing to you today on behalf of PETA and our more than 6.5 million members and supporters worldwide with concerns over the use of live animals on Westworld–especially wild animals, such as the elephants who appeared in last night’s episode. In light of the egregious cruelty and human health risks as well as the public’s growing opposition to the use of animals for entertainment–and because reports say that there are still plans to use bears this season–we’re urging HBO to commit to not using any wild animals in future episodes or other series. All elephants used for TV and film are trained through domination and painful techniques, including the use of sharp metal bullhooks and electric prods. Many animals develop abnormal behavior and become unhealthy, depressed, or aggressive because of the mistreatment that they experience. We’ve identified one of the elephants on the show as Tai, who’s owned and exhibited by the notorious outfit Have Trunk Will Travel (HTWT). This eyewitness video footage shows trainers at HTWT abusing elephants, including Tai, during training. The cruel methods that these trainers use are standard practices in the elephant-training industry. Kari Johnson, co-owner of HTWT, acknowledged under oath that her company chains elephants for more than 12 hours a day. Of the four elephants born at HTWT’s facility, all but one died before reaching the age of 4. Public opposition to the use of animals for entertainment is stronger than ever–evident from the closure of Ringling Bros. circus after 146 years of exploitation and the dozens of travel companies that have pulled elephant rides from their offerings–so it comes as no surprise that we’re receiving complaints from your viewers. And since we sent you information when elephants and bears were used in other series such as Silicon Valley, we’re stunned that HBO would allow this. Captive wild animals also pose a serious threat to the safety of cast and crew. Just last week, director Carlos Carvalho was killed by a giraffe on the set of a TV show with wildlife experts present. There’s no way to predict the behavior of wild animals, and no amount of training can overcome their natural instincts. Dangerous interactions with captive elephants have resulted in dozens of human deaths or catastrophic injuries–including broken bones, crushed pelvises, collapsed and punctured lungs, degloving injuries, head wounds, and brain injuries. Considering the realistic and cruelty-free CGI technology that exists today, all wild animals in HBO series should be computer-generated, just the way the tiger was so beautifully done in last night’s episode. May we please hear from you right away to confirm that any plans to use live bears or other wild animals will be canceled and that you will pledge to stop using and exploiting wild animals? Thank you for your consideration. I look forward to hearing from you. Sincerely, Lauren Thomasson Manager, Animals in Film & Television PETA
