Lorenzo Bianchini is certainly one of the most exciting new director's out of Italy in sometime. He's film's are completely independantly financed and are very stylish. Sadly they are largely unnoticed, but are starting to get some exposure in due part to Dardano Sacchetti who was pointed in his directing by someone over at Nocturne. Anyhow, I have seen both RADICE QUADRATA DI TRE and CUSTODES BESTIAE and can safely say he will being making a huge splash in the Italy market if not the international very soon.
RADICE QUADRATA DI TREIhave viewed the CUSTODES BESTIAE DVD as well and can say it's well worth the money as for one, it'll probably be the only option you'll have for a long time. Dardano Sacchetti's interview sees him complete praise Bianchini a millions times. For me Bianchini's style is unique but he does extract several aspects from classic directors such as Argento, Fulci and even Mario Bava at times..
Yes, his only two film releases are straight to video. He has directed two other films and two or three short films, two of which are attached to each of his DVDS.
