Interesting that imdb has this under the initial title and not the one it seems to be better known for (Scalpel). You'll still find it easily with the title it is marketed (by Arrow for example) and it is a point that gets talked about in the extras of that release too.
Talking about the Arrow release, it is amazing that the original DOP was not just available but went above and beyond to make sure anyone who wants to watch this gets the closest to what he had in mind back when they made the movie! Kudos to him and Arrow for allowing him that (also putting their own version on the disc for anyone to be able to compare and decide which to watch).
But enough about technicalities (although I would argue more than important for the enjoyment), the movie itself is also quite a find. There are always curiosities in the horror world. Movies you may not have heard about, that do deserve to be watched though. This is one of them. It may have notions of other movies (like Eyes without a Face, a classic itself), but that does not take anything away from the movie or the lead performances! Rabid which was released the same year took a similar theme to a different extreme. Both movies are more than fine.
So if you are into horror and like to be scared, I can recommend this highly .. especially when it looks so good as it does ...
