Welcome, Capo Molinari! Hope to see many thoughtful posts from you.
As you see, scripts for the Trilogy underwent many revisions. Quite a few people here have surfaced earlier versions of one or the other of the films that sometimes show interesting nuances or even dramatic deviations from the storylines that actually appeared. But the bottom line always is: what was in the film(s) as shown?
In this case, Zaluchi was never mentioned in the film. He appears in the novel, but as the Don of Detroit.
