A jewel by Brian De Palma, king of the explicit thriller. A riveting story, including one of the more interesting museum scenes ever, surrounds itself with a "passionate score" as is advertised on the DVD. A Criterion film, the extras include in-depth explanations of things you didn't even know you wanted to know . . . but after finding out, you are very happy you did. No dialogue available on the movie, though one can overlook that in order to view the terror lurking in this two DVD offering.
