This is something I have dreamed of doing since I was 12 years old! First, it would have to be longer. A LOT longer, like a miniseries. Even only another half hour or so would help.
I would start the story not in 1904 but in 1884 when they first met. I would include details of both their family lives and characters, like Ella, Ernie, both Sergeis, Sandro, Mathilde K, Xenia, and others who were not mentioned in the movie. I think Ella is especialy important to the storyline,and Anna Vrybova! I would love to have stories of the lives of Rasputin and the Yussoupovs all along, telling background on them and keeping up with their 'adventures' all along. Rasputin's life is very interesting, and there is a lot from Lost Splendor that tells the story of Imperial Russia that I would want to include too. I would have more on OTMA, age them correctly, and develop their characters as people! I would want to show the closeness and lovingness of the family, and not have the scenes where N and A said cruel things to each other, because I don't believe that happened. The one thing the movie did right was to have just the right amount of scenes on the revolutionaries. I probably would not change that much. I would make sure things followed chronological order, like Stolypin being shot before the tercentenary! I would end the story with Joy being taken to England, and the guy taking the dog says, 'how would you like to come to England with me, and be a country squire?' A bittersweet irony, since that is what Nicholas wanted to do.
That would be a great ending but I also would like to add some kind of epilogue as to what became of everyone. The HMS Marborough pulling out of the Crimea in 1919 with the Dowager Empress, the Yussoupovs, Nikolasha and more is also a very moving story. The time they all spent in the Crimea, not knowing if they would live or die, as described in the last chapters of Lost Splendor is a suspensful and entertaining true story as well. I'd like to include that if possible.
