The blurb for this is a little misleading: it is not a drama-documentary, although it does recount the story of its subject's life through the use of newsreel material, combined with striking animated sequences, representing key events.
Its great strength is in the access the film's maker has obtained to people from all period's of the man's life - both his supporters, and those who condemn him. Notable inclusions are his mother, his first wife, his son Pavel, his former business partner, his British mentor, his former head of security at Yukos (an ex-KGB officer), other former employees, and some prominent current Russian politicians. And, of course, Mikhail Khodorkovsky himself - interviewed through the grille of the courtroom cage during his second trial.
Its only weakness is in the rather obtrusive ego of the film-maker, who spends rather too much time telling us about himself, how he became interested in the subject, and his own cleverness in gaining access to so many major protagonists. (This seems a pervasive malaise of modern film-makers - this assumptionm that they themselves are as fascinating as their subjects.)
This gives the film an interminably slow start and is rather redundant, since Tuschi has, indeed, done a remarkable job at getting beyond the myth - both that of his supporters, and that of his demonisers - to an understanding of the brilliant, yet flawed, man himself.
It also proposes the most comprehensible explanation I have yet heard for why, when his fellow oligarchs were fleeing, Khodorkovsky chose to return to Russia.
