For an Italian giallo from 1983, I'd have to say I'm amazed with this transfer. Sure, there's some minor problems, but overall I'm quite impressed. The transfer makes the movie look almost on the level you'd expect from a new movie. The sound is in English Dolby Digital Mono. Score and dialogue are clearly audible with no distortion heard.
Score is fairly decent here too, and definitely helps build some tension at times.
The DVD isn't loaded with supplements, but there are a few nice ones included. It's very interesting overall - a nice featurette that fans will definitely enjoy. The two gentlemen briefly discuss their careers, friendship, and working relationship, as well as how A Blade in the Dark came to be. Also included is a theatrical trailer, talent bios for Lamberto Bava and Dardano Sacchetti, as well as always enjoyable liner notes by Video Watchdog's Tim Lucas. I was also surprised to see a fellow web master Eddie Samuelson getting a special thanks at the bottom of the liner notes, for supplying some art and photos to Anchor Bay for this DVD release.
