One of my favorite early De Palma films (one where he used split screen very effectively--as he did with "Carrie"--to increase the level of suspense and show actions happening simultaneously). Bernard Herrmann's over-the-top score with it's use of the Thermin (much as he did for "The Day The Earth Stood Still") only adds to the weirdness of De Palma's Hitchcockian inspired thriller. De Palma would use many of the same techniques on a variety of films but his mastery here in his early 20's continues to amaze me. As with much of his early film work, there's no denying the influence of Hitchcock on the film (and other directors as well including Welles) but De Palma takes the level of perversity to new heights. The Arrow Blu-ray has been out since last year and I had forgotten about it (it's region free from the UK but can be purchased as an import from Amazon and other places) until recently when I was on a De Palma binge. The special features are quite nice for the film including a visual essay on the film (sadly, there's no commentary tracks), interviews and a gallery ofpromotional materials. The transfer looks quite nice--there's no info on whether a 2K or 4K intermediate or negative was used for the source. The film, by the way, has always looked grainy (a hallmark of many of the new formulations introduced in the 1970's) and the transfer is accurate to the way I remember seeing this in theaters. I had hoped that Arrow would also have a booklet with an essay there as well or some other special hard copy special material (as occurred with Arrow's "Obsession" which came with a miniature copy of the original screenplay by Paul Schrader which differed in the last act). Anyhow, fans of Margot Kidder and De Palma's work would enjoy this.
