    certainly entertaining enough

    This starts very well, indeed, startlingly so with surreal quality about it as we proceed from outlandish and vivid killing to child finding body in trunk of car and something strange going on with eyes. Various persons emerge from secret doors and there is emphasis upon dark glasses and limited sight with some weird sound going off to suggest something untoward is about to happen. Things calm down and killing become a bit mundane, very bloody but not very involving until the end when things spark back into life. Along the way, Anton Differing is effective, if a little one note and Dagmar Lassander lovely as ever. Veteran actress, Valentina Cortese puts in a great little performance and Italian movie stalwart Luigi Pistilli is most effective. Great shots of Dublin and Switzerland along the way and if this is not the finest giallo, it is certainly entertaining enough.

    Weaker giallo with several standout scenes

    After a brutal and attention-grabbing opening murder, this movie settles into a predictable rut. Riccardo Freda seems content to borrow the conventions of the giallo genre--such as giving the killer a recognizable trait like a limp, and then having half the characters in the film limp in various scenes--but manages to suck the life out of them, leaving a rather slow-moving film. Freda is considered a top-notch Italian director but it's hard to see why, especially since his protege had outclassed him and positively defined the genre the year before. Still, it's done with enough care to have (apparently) taught Brian DePalma a thing or two when it came to "Dressed to Kill," and the finale has a jaw-dropping viciousness to it that has to be seen to be believed, involving a nude 16 year-old, an old woman and a completely berserk black-gloved killer. It's just a shame that the scenes between the violent ones aren't more involving and interesting.

    Rough around the edges but interesting giallo!

    Hi, Actually some of this film was made in Waterford, including the 'bridge in the fog' and river scenes. I was an eighteen year old working as an assistant in a chemist shop on the quays in Waterford when some of the crew came in and asked my boss Michael F. O'Connor to make up a concoction that would fizzle like acid when thrown on the victim. This he duly did, after some experimentation! They spent at least three days in Waterford. This was a very exciting event for me as I was a huge movie buff, and I still am of course! I have the DVD release and also the soundtrack composed by Stelvio Cipriani. Great memories. I would be glad to hear from you if you ever read this message. Niall.

    Gory giallo with some unusual ideas

    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.

    "L'Iguana dalla lingua di fuoco" aka. "The Inguana with the Tongue of Fire" is certainly not a very memorable or spectacular Giallo, but it is still a pretty entertaining film that I recommend to my fellow Italian Horror buffs. The film, which is brought to you by director Riccardo Freda ("Lo Spettro", "Murder Inferno",...) has its flaws, but it also has quite a bunch of highly memorable elements. The film takes place in Ireland and, as far as I know of, this is the only Giallo ever set in Eire. The plot may not be the most original, and the twists sometimes seem a bit silly for Giallo standards, yet this is very cool in some aspects. The film has an eerie general mood and is often quite nasty, with gory murders, and the great Italian actor Luigi Pistilli in the lead as an investigating ex-cop. Pistilli truly was one of the greats in Italian cult-cinema, whose great performances complimented masterpieces of a variety of genres, such as brilliant Westerns ("For A Few Dollars More", "The Good The Bad And The Ugly", "The Great Silence"), ingenious Crime-Cinema ("Milano Calibro 9"), sublime Gialli ("Your Vice Is A Locked Room And Only I Have The Key", "The Scorpion's Tail") or Mario Bava's blood-soaked slasher landmark "A Bay Of Blood", just to mention some of the most memorable films the man has been in. And Pistilli once again delivers a great performance as the former Detective John Norton, a Dublin ex-copper who lives with his teenage daughter and his almost deaf mother. After a murder near the Swiss embassy, other violent murders follow. Since the police don't find any clues, the ex-detective Norton is appointed to the case... As mentioned above, the murder sequences are quite gory and nasty (if sometimes a bit clumsy). The score is also excellent, which contributes a lot to the atmosphere. The film also has some silly elements, such as a shrill tune whenever something eerie happens, but never to an extent that would lessen the entertainment-value. Pistilli is great, and the rest of the performances are not bad either, Anton Diffring is wonderfully arrogant as the Swiss ambassador, Irish actor Arthur O'Sullivan is very good as a grumpy elderly Police inspector, and beautiful Dagmar Lassander makes a sexy female lead. All things considered, this film is certainly no Giallo-highlight, but it is an overall entertaining flick that is well worth watching for Italian Horror buffs.
