The critically acclaimed 2012 film "Life of Pi" tells the story of a boy lost at sea with a tiger, so a large portion of it was shot on the water. While the bulk of it was CGI, plenty of scenes involved a real tiger named King, whose scenes were shot in a tank. The Hollywood Reporter which compiled a report of alleged abuses on film sets, claimed that during one scene, King nearly drowned and had to be dragged to safety with a catch rope. Gina Johnson, a representative for the American Humane Association, was said to have stated in an e-mail, "I have downplayed the f--- out of it." Johnson left the AHA a day after the the e-mail came to light.
