This is an unknown gem. The plot may not altogether plausible, but not impossible. The acting is superb. As one who is attracted to this period of history it gave a twist that I would have changed, however slightly. I’ll leave that to one’s imagination though. But as to the film it richly deserves much greater acclaim as a most intriguing film. Plummer is, as usual, just brilliant. See this movie.
And it is quite interesting that Plummer played the piano himself. He was, in fact, trained as a consent pianist before he became the consummate actor he is today even at age 91.
