The Bird with the Crystal Plumage;

The film's elevator murder originally culminated with the passenger's face repeatedly slashed by a straight razor, but the United video I saw cuts away just as the razor begins its deadly descent.  thanks censors. 

 The Japanese laserdisc of Suspiria is not presented with its widescreen framing intact, causing an occasional awkward composition that sucks cuz its all about wide screen.

and Dario Argento is the King of all Giallos
