This scene, which was filmed in 2006, was only the beginning. In 2011, Will passed away of old age, but not before finally learning what it meant to be a lion.
"He had five years of tranquility before he died. Here he had the opportunity to interact with other lions. He loved to lie in grass and look at the sky," sanctuary founder Marcos Pompeo told The Dodo. "He was a very happy lion."
