I'm watching (and really enjoying!) The Optimists / Оптимисты (2017) about Russian spies in the 1960s.

And thus I can tell you that Yuriy Kuznetsov who plays Vareynikov (the mentor) n also plays Boris (the old guy) in To The Lake, and Severija Janusauskaite who plays Ruta Blaumane (the department head) also plays Svetlana Sorokina (who sings at the club) in Babylon Berlin.
