Judging by the comments, yes.
This fictional politician's problems almost perfectly mirror those of the real-life Roman Polanski.
and,
a comment on Polanski's own situation or as supporting the case he made in his 1984 autobiography: "As far back as I can remember, the line between fantasy and reality has been hopelessly blurred."
I'm looking forward to seeing it.
Btw - the autobiography mentioned in the quote is a great book, fun to read.
