Fellow Giallo-fanatics: beware and/or proceed with caution  for this movie isn't exactly what it appears to be. It surely looks like a Giallo, with its juicy VHS cover (showing a busty naked girl and a big bloodied knife), rhythmic title and the names of two veteran Italian actors in the cast (John Phillip & Fernando Rey), but it's basically just an erotic thriller without much of a plot. The version I watched is presumably harshly censored  with a running time of barely 77 minutes  but then still there's a severe lack of suspense, character development and most of all sadistic (and typically Giallo) carnage. "Eyes Behind the Wall" can briefly be summarized as the gathering of a bunch of perverted characters and the extended depiction of their sexuality issues. It's an interesting effort notwithstanding, because writer/director Giuliano Petrelli (his only film) clearly attempted to do something special, but the overall result is unsatisfying and regrettably tame. Inspired by Hitchcock's "Rear Window", the main character is a frustrated elderly and wheelchair-bound writer. He and his much younger lover get their sexual kicks from spying on the single male tenant living across the road. The tenant, respectively, likes to perform gym exercises around the house whilst being naked and clearly has bisexual desires. Wheelchair guy sends his wife over and they have sex. Then, there's also Ottavio the butler who repeatedly rapes schoolgirls. Are there any normal characters in the story? Well no, of course not! The film benefices from a continuously ominous atmosphere, with a moody soundtrack and nifty photography, but none of it ever leads anywhere so it's all just sleaze & sex without significance. There's a truly bizarre twist/revelation at the end of the story, but it comes too late and too randomly to boost up the overall quality. Not recommended to fans of Italian horror/cult cinema, but maybe it is great viewing for psychology students, to analyze the characters Freud-style.
