When I first saw the trailer for this film and having in mind his previous hits 'Gladiator' and 'Kingdom of Heaven' I thought this is a film I will enjoy. Well, I went to watch it last Thursday and left feeling somewhat underwhelmed. Overall, the film felt disjointed, scenes in Paris being followed without any explanation by battle action. For instance, Napoleon was crowned (or crowned himself) emperor and before you know it, he is at Austerlitz. The battle scenes were well presented, though, as usual, the cavalry charges were long distance gallops, rather than the more measured advance the regulations prescribed. In addition everything felt rushed, perhaps the subject matter was too great for just one film? One curious move was to have the infantry digging shallow trenches at Waterloo, not something I have ever come across when reading about the battle. Also, at the end of the battle the Prussians seem to be coming from the French left (ie the west) rather than the right.
Joaquin Phoenix is too old to play a 24 year old at the siege of Toulon (1793) indeed he doesn't seem to age at all between then and Waterloo, over 20 years later. This again would support a two film approach, however, given the costs involved this is unlikely to happen. As a spectacle the film succeeds, as a film about Napoleon, I feel it misses the mark.
