There's nothing I can say about this DVD, that hasn't already been mentioned in Michael Mackenzie's review over at DVDTimes. Nevertheless, let me show you a few examples of the issues he points out. First, the interlaced / non-anamorphic transfer of the feature presentation vs. the progressive / anamorphic trailer (note that the latter uses a different shot for every scene, which makes a direct comparison impossible):

Regarding the extra shots in the trailer - an issue I myself fussed about in the review of "Der Rächer" - I think this might be a common practice, and does not necessarily mean the film is cut:

About the framing, it seems indeed a bit tight. Michael suggests that the film might have originally been exhibited in a wider aspect ratio. On the other hand, the cramped head-space (particularly visible when compared with the below bootleg DVD+R release framed at 1.71:1) suggests that the intended ratio was perhaps closer to 1.66:1, an AR not uncommon for the gialli from that period:

And now, to conclude this review, here's a lil'something for my friend tomiisek, a great admirer of Jean-Louis Trintignant: ;-)
