Louis Zamperini lived just about one of the craziest lives imaginable. A first-generation American, he went from being a young punk who grew up during the Depression and was the scourge of local law enforcement, to being an Olympian who ran in the Berlin Olympics and got a personal meet-and-greet with Hitler, to being a bombardier who fought against Axis forces in the second World War, to surviving on a life raft in the Pacific Ocean for 47 days while eating raw fish and drinking rain water, to being held in a Japanese POW camp, to eventually being a married man and motivational speaker. It’s the sort of story that Hollywood loves to turn into movies. But, due to all of the inherent drama in the subject matter and the delicacy with which it needs to be handled, it’s also the sort of movie that Hollywood tends to turn into sappy melodramas. So, seeing as Zamperini’s upcoming biopic, Unbroken, is being put together by Angelina Jolie, who’s only had one previous go-around at being a director (In the Land of Blood and Honey), sappiness is certainly a concern. There are a couple of indications that Jolie and company are going to get the execution right on this one though, and now that the film aired a teaser during the Olympics, we’ve all got a much better idea of what to expect.
