In pic 18 we have Ugo Ballester on the right with a wig.
The older man in pic 50 is very important for me, he infact is Giuseppe Righi a very famous fotoromanzo actor, one of the busiest in the 1960's-early 1970's, but i have problems founding him in movies, this is actually his 2nd movie role i found for him, so we only need a third one and he will have his topic too !
I think the older man in 85 is the Elegant old party guest
