My brother just sent me a link to this, and I had to share it.
In no uncertain terms, it is the best Maniac poster I have seen yet.
Perfectly captures the sadness and pathos of the character.
Without the ridiculous Caroline Munro character, the film would have been drastically elevated to a dark character study. For mine, this poster IS the dark character study that Maniac, unfortunately, is not (even though I remain a fan).
