I have never before read or heard about it and I doubt Dario has ever mentioned this. For those who have never seen Trauma,please don't read the rest of this post... SPOILERS AHEAD In a scene at the end of the film,after Rydell and Asia are captured and Macaulay Culkin is already in the house,Dario links Piper Laurie to Madame Guillotine.Both "famous" for their beheadings. The way Dario films the window and its curtains.It's a strange window indeed... I think it's very cool and I'm convinced it's intentional.But as I said,I have never heard or read anything official about it. Here it is: On a side note.The first time I watched the movie I already knew Piper Laurie was the killer..Rydell and Asia both as protagonists automatically made Piper Laurie the killer.Such a big name and than to be killed in the first part of the movie?No way! Trauma is a very nice Argento movie with a few flaws.But hey,an Italian production without any flaws has yet to be made Last year I bought the UK Optimum release and it's a nobrainer. It's scenes like the above that make this movie a worthy addition to the Argento collection.
