The HBO film "CITIZEN X" was a good flick about the "rostov Ripper" a guy name Chickatillo (I think thats how ya spell it). It had sevearl good performances and Donald SUtherland got a Golden Globe and EMmy for his role as a tired but pushy colonel of detectives in Rostov. I believe it was made in the late 1990's and can probably be downloaded from Netflix or HBO store.
Id give it 4.5 stars out of 5 because you know it was filmed out of country.
