If you enjoyed this you should also try and see Kinski in Sergio Garrone's gothic horrors LE AMANTI DEL MOSTRO and LA MANO CHE NUTRE LA MORTE where he gives a manical standout performance,both films are quite similar in mood and style to D'amato's effort though much better imo.
I must say I like Death Smiles and am interested in the 2 other titles mentioned,but where to find them?

I noticed Le Amanti is out on Spazmondo,would that be a good buy?
