We can begin with PIETRO GIUSEPPE ORO
He is credited both in the theatre scene, but he is credited to appear also in other scenes of the movie
And infact i think that pietro is this man.
Look at the left the old man with no hair in the middle
Well i think that this is the same man in this other scene:
Not only pshically for me he is the same person,but he also had the same dress if you can see !
So i think that Oro is this man,any opinions ?
