I first read about Mad Mike Hoare in the pages of Soldier of Fortune magazine back in the eighties. I had seen The Wild Geese back then, but really had no idea about the background and it’s relation to MMH. The title of the movie was inspired by the 5 Commando patch that MMH wore, which also had a flying goose. MMH also wrote a ton of books about his exploits, so there is that resource as well. Richard Burton’s character was said to be influenced by MMH, and MMH was an advisor on the film.
