You can read a review of the movie here and watch the trailer (in German) here. [Unfortunately, the review transposes numerals in the date and describes the events as happening in 1653 instead of 1563, calling the drama an "entertaining romp about epic 17th century [sic] conflict with lots of fighting in court, on the battlefield, and in bed."
According to Variety, the film has scored buyers from Eastern Europe to South America, but so far no word of North American sales. If anyone catches the film in Europe, I'd love to hear what you think. Henri VI seems to cover much of the same ground as the 1994 film La Reine Margot, starring Isabelle Adjani and Daniel Auteuil; it would be interesting to compare the two films and see whether Baier has a new take on the material.
