Volontari per destinazione ignota (1978, TV movie released also in theaters), credites as Natale Nazzareno, as The sergeant
Listed in Radiocorriere TV guide

Scoop (1992) (TV mini-series) - episode 2: "Segreto professionale" (Part 2) as Cosimo Salento.

All three episodes of this series are two-part episodes, and Nazzareno only appears in the second part. He should be credited, but the credits were cut from the copy I watched.

La primavera di Michelangelo (A Season of Giants) (1990) (TV mini-series). Nazzareno is credited in all three episodes but only appears for a few seconds in episode 1, as Foreman.

No il caso è felicemente risolto (1973) as Augusto, the coachbuilder (credited)

Giù la testa (1971), credited, but not found. Said to play a Train engineer, I could not find such resembling him, nor another role. On the other hand, in this film there's myriads of people lying around dead or doing what they do in their lives.

I giorni dell'ira (1967), credited as "Natale Nazareno" but not found so far

Don Matteo (2002 TV series) Season 3, episode 1: "I segreti del cuore", credited as "Nazareno Natali", as Antonio Arania, a worker in a factory who is under suspicion for being a murderer.
