Firstly, this film is well produced and well acted, but unfortunately the screenplay leaves a lot to be desired. Matthias Schweighofer plays his character with depth and feeling, but bears little resemblence to the real Richtofen. The latter was a trained Prussian officer with a high sense of duty and a ruthless attitude to both his enemies and subordinates. Schweiger's portayal shows a playful youth with an easy going nature who becomes openly critical of the German high command, which behaviour Richtofen would have regarded as undisciplined.
The air scenes are exciting and care has been taken to show aircraft of the time, although the dogfight scenes look like something from a computer game. The night fighting scene is pure make-believe but visually dramatic.
No real effort is made to follow Richtofen's life (after all, the title is The Red Baron!). A spurious relationship with his nurse is turned into a central part of the film, and she is shown wandering around the fighter airfield, which would have been off limits to civilians. Joseph Feinnes plays an enigmatic allied officer who meets up with Richtofen in no-mans-land, which just adds confusion to the story- he seems rather wasted in this role.
As a bit of light relief for the computer game generation, this film is fun but shouldn't be mistaken for history. It's full of mistakes but worth watching- at least it isn't the usual gung-ho Hollywood cobblers. Note; this is a review of the original German version, so the English release may differ.
