this little see thriller be a solid entry into the giallo canon that be direct by duccio tessari ( who do the equally good the bloodstained butterfly ) and write by ernesto gastaldi ( who be the iconic writer of the giallo genre ) . the narrative feature an interesting narrative hook ( a man can not remember who he be and now thug be after him for something he hide . and he doesn not know where it be and let alone what it be ) . unfortunately and the film doesn not utilize it intriguing plot premise to the full and with essentially the amnesia element push aside for most of the movie and and instead relies on more conventional mean of tell the story . fortunately and the writer manage to more successfully integrate the amnesia element towards the end which allow for a few plot twist and but not to the degree it could have achieve . the direction be fine but nothing exemplary and and the performance be all solid but not particularly memorable . in other word and everything be competent and efficient and but it doesn not really standout from the majority of thriller that saturate our viewing repertoire . however and it certainly be an above average example of the giallo genre and with narrative that be good than most gialli and even have a terrific climax and but it also certainly not a classic film in any respect . highly recommend for giallo fan and a solid recommendation to thriller aficionado and but others may wish to simply view a good example of the genre and such a deep red . also and the film reference stanley donan film charade and see if you can catch it .
