There was a superb documentary about the story of Hercules the bear on Channel 5 last week. Its available online: Hercules The Human Bear | Channel 5 Hercules was a male brown bear, born at the Highland Wildlife Park and kept as a pet by wrestler Andy Robin: Hercules the Bear - This is the official website, dedicated to his memory
Finally got round to watching this and I would echo Paradoxurus' recommendation. It showcased the "different-ness" of the 1970's well and in particular I was struck by how vast Hercules' enclosure seemed compared to many of his peers in that era.
