Yeah, it came out in 1981, but it fits right in with the Golden Era of Adult Crime-Dramas of the 70s, many of which can be found further down this page. UA didn't know how to sell it (as is evidenced in this trailer) or it would be far better known today. But those who have seen it can testify to its greatness. I wish a special edition Blu-Ray would see the light of day, but I doubt it will ever happen. You'll have to settle for a plain wrapped DVD with no extras.
The book (CUTTER AND BONE) by Newton Thornburg is also terrific.
