This Film
I especially enjoyed the young actors who portrayed Prince John. Miranda Richardson also did a good job as Mary. However . . .
Alexandra, especially, was totally unconvincing. They had her speaking English with what I assume was a Russian accent. Alexandra never really learned to speak Russian that well--she didn't start at least until Nicholas proposed to her. In deference to his wife's difficulty with Russian, the imperial couple usually spoke English at home--French, of course.
I do not understand why Mary and George were so cold to their children. Perhaps this explains the future George VI's bad stammer and Edward VIII's becoming such a wasted, unfocused individual. King Edward and Queen Alexandra were certainly loving grandparents--the film got that right anyway--so George couldn't blame his parents for his coldness.
The film was, on the whole good, and I appreciate their bringing this forgotten boy to light.
