Synopsis from IMDb: An American writer in Rome is stalked by a serial killer bent on harassing him while killing all people associated with his work on his latest book.

What. A. Film. Easily Argento's most thematic film, full of underlying subtext, eroticism, the stigma of sexual humiliation, the film follows American writer John Saxon (of Enter the Dragon and ...Elm Street fame) on his Italian ordeal at the ends of an obsessed 'fan'. Literally drenched in gore shots, the film has had a tumultuous release history, even ending up on the DPP's Video Nasty list. Not getting a proper re-release until 1999, unless you count the AWFUL Unsane, which had all of the killing cut out, it's only in the last 10 years that people have finally got to see what all the fuss was about. Look out for the stunning single take shot leading up to one of the murders, it's simply breathtaking.
