From the DB credits page: the guy on the right is not c.s.c. actor Renato Terra, I identified him a couple of years ago - together with the correct roles for Lorenza Guerrieri and Corinne Fontaine - in Requiescant/Kill and Pray, in which he plays Alonso (see below).
Black and white screenshots are from Pasolini’s Accattone (1961, left) and I due evasi di Sing Sing (1964, right), with Franco & Ciccio.
Practically all the pics in the thread below are consequently wrong, with the exception of the Kill or Be Killed one.
