When it comes to rare and forgotten gialli I want to see them all.So my next choice was "Assassino Senza Volto" aka "The Killer Without a Face".A series of murders happen in an old Italian castle.The unknown killer dispatches his victims by shooting them to death with a pistol.Barbara,the unhinged owner is the chief suspect.But not everything is quite as it seems...The film is set in the Balsorano Castle and is shot in expressionistic black-and-white.The action is pretty dull,albeit there are some mildly suspenseful stalking scenes.There are also a few interesting visuals on display here and there but on the whole "The Killer Without a Face" is far too slow moving to be of interest to most genre fans.5 out of 10.
