Yes that's true, I think it's very respectful but if I really want to respect the tsarevich (and give a part of my life to him) I would make a whole movie about his life and dedicate this movie to him ! Of course it seems ridiculous and it's a dream because I'm not a movie director (but it would really interest me), I don't think Warner Bros., Universal or even a little cinema studio would help me and the spectators would not necessarily watch the movie but in fact I don't care, I wouldn't make this movie for money but only because the tsarevich interests me a lot and in order to instruct ! Everything would be true and checked by several specialists, biographers and nothing would be hidden to the spectators (not even the crisis of hemophilia in 1912 nor the execution in 1918 and the 2 bullets in the head !). In fact, history is extremely important to me and I think that hiding violent facts isn't always a good thing (in a realist and historical context) and I'm not one of these guys who thinks that when someone sees a violent scene he wants to make the same thing... I would also want every details to be extremely realists : every protagonist's face would be made by a computer program and by computer scientists helped by hundreds of pictures representing Alexei (and his family) when he was 1, 2, 3... 12, 13 and almost 14 ; all the protagonists would speak in Russian (with subtitles) and I don't want to "cheat" with the spectators' emotions with a melancholic music (I really like music in films but I think it's really too easy - but not realist at all ! - to move the spectators with it) simply because in reality there wasn't music (lol) and because I think that a good movie about the Romanov should move the spectators "without" that kind of "emotional artificiality".
Well, even if the tsarevich probably didn't even realize that movies could be used as biographies (about some important persons or himself !), I think it's extremely respectful and a huge homage to tell his history with as much details as possible (even if some persons think it's disturbing, which can be understandable).
(I have to break this up into two posts LOL)
Apparently you have never seen a film with the works of Maurice Jarre, Nino Rota, George Fenton, Patrick Doyle, Thomas Newman, Alan Silvestri, Elliot Goldenthal, Howard Shore, Trevor Jones, Randy Edelman, John Barry, Mark Isham, James Horner, Ennio Morricone, Elmer Bernstein, Gabriel Yared, Michael Kamen, James Newton Howard, John Debney, or John Williams. These composers are famous for doing historical epics, or historical fiction, and were acclaimed highly for their efforts. (Jarre: Doctor Zhivago, Lawrence of Arabia, Rota: The Godfather, Fenton: Anna & The King, Doyle: Henry V, Newman: Road To Perdition, Silvestri: Forrest Gump, Goldenthal: Michael Collins, Shore: Gangs of New York, Jones: Richard III, and he and Edelman corresponded together for The Last of the Mohicans, Barry: Dances With Wolves, Isham: Bobby, Miracle, Eight Below, Fly Away Home, Invincible, The Black Dahlia, Men of Honor, Horner: Apollo 13, Braveheart, Troy, The Perfect Storm, The Four Feathers, Glory, Titanic, The New World, House Of Sand & Fog, A Beautiful Mind, Morricone: The Mission, Bernstein: The Ten Commandments, Yared: Cold Mountain, The English Patient, Kamen: Robin Hood: Prince of Thieves, Newton Howard: Hidalgo, Charlie Wilson's War, Michael Clayton, Blood Diamond, Freedomland, From The Earth To The Moon, Wyatt Earp, Alive, Debney: The Passion Of The Christ, Williams: Saving Private Ryan, 1941, Seven Years In Tibet, Munich, Memoirs Of A Geisha, The Patriot, Empire Of The Sun, Schindler's List). I think you should be more educated in the film score field before making such a drastic mistake if such a movie were to get off the ground. Unfortunately, Rota, Bernstein and Kamen are deceased now, but the others are still around and quite eager to be a part of such a powerful project. Williams and Horner in particular should be intriguing possibilities, because of their extraordinary work on Apollo 13 and Schindler's List. I guess you haven't seen Schindler's List, but that is the direction you want to go when making a historical movie, it's sheer perfection, and the score works extremely well with it. Before making such a rash judgement, I advise you see Schindler's List.
