I found this interview with Steven DeKnight, the showrunner for Netfilix’s upcoming series based on Marvel’s Daredevil, on Superherohype. He actually give very little away, but does say that the series takes place in the 1970’s and that Vincent D’Onofrio is a really scary Kingpin.
He also mentions that things are going really well, though I suspect that he could be making the next Heaven’s Gate, and he would probably say the same thing.
