Cirillo Konopleff was born as Kirill Grigor'evič on 9 June 1882 in Abastumani (then a part of the Russian empire) and died on either 29 July or 1 August 1956 in Rome, Italy.1
He lived in Rome, in Via Palestro, 69.2
A very distinctive-looking man with a bald head, large moustache and often seen with monocle, he was a family friend of the last tsar of Russia, for whom he also served as a cavalry colonel in the army. Following the October revolution of 1917, he sought shelter in Italy, where he ended up appearing as a generico in several films made during the 1930s, 40s and 50s.

Some further titles that Cirillo is supposed to appear in, but for which I've not been able to find copies...

Cirillo is missing!
As is apparently always the case, there are some titles where Cirillo is listed as appearing, but in which I can't find him...
- Giuseppe Verdi (1938) Listed by ANICA with no role given. I couldn't spot him anywhere, but there's an endless crowd of audience members in some of the opera scenes and most of them are never clearly seen, so it's very much possible that he appears in some of those scenes but without being visible on-screen.
