(FILES): This January 25, 2012 file photo shows US actor Dustin Hoffman arriving at the premiere of HBO's "Luck" at Grauman's Chinese Theatre in Hollywood, California. A hit US television series starring Dustin Hoffman has been canceled after three horses died during filming, the channel which makes the show announced March 14, 2012. "Luck," about thoroughbred racing and also starring Nick Nolte, launched in January and had already been picked up for a second season, with production mostly at a horsetrack east of Los Angeles. But a first horse died on the set in 2010 and another died last year. Then a third animal had to be put down on March 13, 2012 after falling backwards and striking its head, despite new safety rules put in place. AFP PHOTO / Files / Robyn BECK
