ANIMAL rights group Peta has called for TV and film safety rules to be tightened after two horses were put down during filming for HBO drama Luck. The animals were injured in the making of the show starring Dustin Hoffman. Rights group Peta said it “repeatedly reached out” to HBO before filming to offer safety advice but was “rebuffed”. HBO, which worked with the American Humane Association, said both were “committed to ensuring all necessary safety procedures” were in place. Luck, conceived by NYPD Blue creator David Milch, is billed as “a provocative look at the world of horse racing - the owners, gamblers, jockeys and diverse gaming industry players”. The first episode - shown in the US on 29 January - will be broadcast in the UK on Sky Atlantic on 18 February. The AHA said in a statement that the fatal accidents had taken place several months apart - one during the filming of a pilot episode and another during the filming of the seventh show.                                                  –BBC
