There's still no reasonable release of this rather unknown giallo. The US DVD, released by Eurovista, seems to be based on a VHS without any remastering, furthermore the image is cropped due to Pan & Scan. Nevertheless there are two really interesting interviews with Barbara Bouchet and Rosalba Neri on the DVD, but they're quite short.
The VHS, released by Something Weird Video, is probably the only release which contains the movie in its correct aspect ratio. Presumably it's based on a copy for movie theaters, but there's also a huge disadvantage: approx. 20 min have been removed which is, escpecially in the final sequence, really annoying.
