Fragment of an Empire (1929)

Director Frederick Ermler’s last silent feature and the last of four collaborations with actor Fiodor Nikitin. Nikitin plays an officer who spends a decade after the Great War as a shell-shocked amnesiac, until a glimpse of a woman through a train window sparks the return of his memory. He makes his way back to St. Petersburg, now Leningrad, a man out of time who struggles to make sense of the new society brought about by the revolution.

Unfortunately the movie Fragment of an Empire is not yet available on HBO Max.
