This is a good example of a co-production where the Italian and Spanish cast lists differ significantly from one another. The Spanish cast list omits several the minor Italian actors (Facchetti, Mingozzi etc), but instead include several minor Spanish actors who are not listed in the Italian cast list.

These are the complete Spanish cast credits

Oh, and the first unidentified black mass participant is David Thomson.

I don't know his identity, but the "Inspector" looks to be a Spanish generico with a similar look to Felipe Urmeneta, who I have collected 5 or 6 roles for and will make a topic for once I have a few more
