Apparently they've approached Chris Noth and Sam Waterston about it, though the article doesn't say if or how either responded.
http://tvline.com/2015/02/06/law-order-limited-series-nbc-chris-noth-sam-waterston/ I hope this actually happens, and of course that it doesn't stink. I tolerate SVU and the CI versions, but always found a lot of aspects about both shows to be ridiculous. Any other L&O Original fanatics on here? I'm gradually piecemealing a collection of the L&O seasons through Amazon.
