If my original career plans had worked out, this is exactly the kind of film I would have directed.
Yet again Mario Bava delivers the goods. This is an excellent gothic chiller with some pretty startling imagery thrown in. I was also delighted to discover that I unwittingly paid homage to this film in a student project back in 1993 when I made a film of myself running through a room over and over again, caught in a loop.
It is unfortunate the the English language title is somewhat misleading as it sounds more like a Eurospy or fumetti. Mind you Operazione Paura is not much better.
Arrow's blu ray presentation is fantastic, as usual.
