I just dug my VHS copy out and started watching it again, I have to say it is really well made. I know I saw it once before when I fist got it, but for some reason I could not remember anything about it. I would really recommend this film even though it doesn't have subtitles, but you can probably figure out what's going on if you know the general storyline.
Apparently the main character, Malcolm McDowell, who plays the mental patient, thinks he is Yurovsky, and also Grinevitsky, the man who killed Alexander II.
