Le vampire noir

A remake- though not exact - of 'M' has a Peter Lorre-like actor as a pedophile murderer (none of that on-screen fortunately). The cinematography is good - especially the ending scenes in the sewers, 'borrowed' from the Third Man.

A madman is loose in Buenos Aries, kidnapping and murdering young children and in general baffling the police. There is a sub-plot, the prosecutor has an unhealthy interest in the only witness to a childs abduction.

All this may have been cutting edge in the Argentine post-Peron era, but unlike the first few reviewers I see nothing remarkable here. The acting is less than average Hollywood of the same time, the story was told better before and after this. And you have to suffer through sub-titles also😁
