Riccardo Freda is an Italian director often cited for his style, however very little of it is in evidence in the admittedly wonderfully titled "Iguana With The Tongue Of Fire"; instead, we get the dullest police investigation scenes in history, and a few ludicrous red herrings (like a man cutting himself shaving but leaving the razor all bloodied up lying around!). And there is also the old "I know the killer but I can't tell you over the phone, I'll meet you later at....aaaaaaargh!" ploy. You may struggle to finish this film. *1/2 out of 4.
