In Dublin, a young woman is brutally murdered in her home by a maniac that throws acid in her face and then slits her throat with a razor. Her mangled body is later discovered in the boot of a limousine owned by the Swiss Ambassador Sobiesky. The Ambassador, who was the dead woman's lover, refuses to cooperate with the police due to his diplomatic immunity. John Norton, an ex-cop famed for his brutal working methods, is brought in to help and gets too deeply involved when he stars an affair with the Ambassador's beautiful step-daughter, Helen. Meanwhile, the brutal killings continue... Written by Anonymous

Gory giallo with some unusual ideas
24 October 2000 | by (Zürich, Switzerland) – See all my reviews

Riccardo Freda's rude giallo is not quite a masterpiece, but it still delivers good entertainment and some stuff quite unusual for the "typical" Italian thriller of the Sixties and Seventies. First of all, the movie plays in Dublin, which I already assume unique in the history of giallo. Second, the family involved in the crimes is the one of the Dutch ambassador in the Republic of Ireland, which makes the case even more complicated for the policemen involved.

Also very remarkable is the fact that this giallo delivers no nude scenes, which is quite rare for this genre. And last but not least, it's one of the goriest gialli before Dario Argento made "Profondo Rosso" (Deep Red). E.g.: Some hapless victims get their faces mutilated by acid before the killer slits their throats.

By the way Freda delivers some thrilling and uncanny moments, and the climax is extremely nasty for various reasons: It has to be seen to be believed. The cast - including Anton Diffring, Luigi Pistilli, Dagmar Lassander and Werner Pochath - is above average and always convincing.

All in all, "L'Iguana dalla Lingua di Fuoco" is not a masterly but still very cool giallo. Its only fault (possibly) is that it's too nasty for the easily offended - but easily offended people don't watch gialli anyway, I guess.
