No biographical details are currently known.
It looks like he only has 10 credits as an actor, all in very small roles, plus an equal number of production credits which I will list separately.
I already had Luciano saved as a potential generico in 5 films before I identified him, only 2 of which matched with the 17 roles listed by IMDb, so there is a strong probability that there are further roles to be found.
