I watched Phenomena twice last month. I managed to catch it on the big screen (I was really excited about this, but slightly let down when it turned out it was a DVD, rather than film that was projected) and also picked the R2 Medusa DVD up. This edition contains the Integral version of the film (with English subs). Never watched the film in Italian before and it was a slightly strange experience to see the film without hearing Jennifer Connelly's and Donald Pleasance's voices. Unfortunately the misplaced heavy metal was still there though.
