Compared to other Italian genre films (Giallo, crime etc), sw’s doesn’t have that much nudity. Mainly just in some of the late spaghettis from 70’s like 4 of the Apocalypse or China 9, Liberty 37 (I haven’t seen it uncut but it should have lots of nude scenes, my version had none).
Blindman is probably the most famous sw for having lots of nudity. Also Corbucci’s The Specialist comes to my mind.
Any others ?
