There's a lot of talk about how so many movies these days are just derivatives of older intellectual property. While it might be the case that a lot are made from premises that first appeared on old TV shows or in the films of yesteryear, it's also important to remember that sometimes franchises go back a lot farther than you might think.
For instance, the television program Little House on the Prairie, which aired from 1974-1984, was based on an even older series of children's books. The first of these was published in 1932, so the news from Vulture that Sony is looking to make a movie from the series isn't as crass as you might think. In fact, the books are such classics that it's hard to believe there isn't already a film version of them yet.
It also helps that historical dramas are getting a lot more accurate and realistic than in the past. The harsh realities of growing up on the Great Plains probably would have been whitewashed with a lot of sentimentalism thirty years ago, but today it might be possible to tell a gritty and honest story about frontier survival. Word is that David Gordon Green will likely direct, and his 2003 film All the Real Girls could serve as a template for the budding maturity of the girls in the Ingalls family.
