Remakes are always defended in ways that make the general public appear as idiots. Old films are remade because people don't remember, foreign films are remade because people don't like to read subtitles and documentaries are remade because they teach us stuff. But any documentary that can be remade as a dramatic feature is different from docs that just teach us stuff. They already have an engaging narrative and interesting characters -- otherwise producers wouldn't see the remake potential. Rather than finding new ways to market enjoyable docs to moviegoers, I guess it's easier to do the remake, so filmmakers have an easy movie to make and sell, therefore providing two films to be profited on.
I guess the reason that I'm even more angry this time is because Murderball, which has inspired an upcoming project for director James Mangold, is probably the most entertaining, most easily accessible documentary that has ever existed. Sure it teaches us stuff, but it's also hilarious, action-packed and feel-good. Besides, nobody could play lead murderball (aka wheelchair rugby) player Mark Zupan in a way that would better his own appearance in the Oscar-nominated, Sundance-winning doc. Certainly not Eminem, who expressed an interest last year.
