One thing that Der Rote Baron has in common with an earlier WW1 air-war film, namely 'Von Richthofen & Brown' from 1971, is that
Lanoe Hawker is portrayed in both as both fighting and dying whilst flying an SE5. At least the earlier film had the excuse that at that time, no airworthy vintage DH2s were available and CGI was still in the future. But the Red Baron, with its impressive CGI capable of recreating any aircraft of the past, has no such excuse.
One theory is that film-makers probably have the attitude that the DH2, whilst its qualities may be well-known to the aviation buffs, would look fragile and quaint to the ordinary 'layman' film-goer. To an audience member with little or no prior knowledge of WW1 aviation, the DH2 would look like something out of 'Those Magnificent Men in Their Flying Machines'. They would wonder how the Baron could ever have such a hard time bringing down something that looked as about as threatening as a glider constructed out of matchsticks and glue.
Many war and historical films have taken liberties like these in order to make a story more easier to understand and more agreeable to the majority of cinema-patrons who come to a film with little or no prior knowledge of the historical events they are witnessing being depicted on screen. The downside of this is that certain film-makers can distort or even falsify history and ensure that audiences come away with a slanted or in-correct view of the events portrayed.
Many liberties and instances of poetic license may be niggling to aviation and historical buffs but are pretty much harmless. Take one example such as the recent film 'Pearl Harbour' (2001) in which the Mitsubishi Zeros were painted olive-green, instead of the more accurate pale-grey. The director Michael Bay acknowledged the error but he admitted that the Zeros had been depicted thus so as to make it easier for the cinema audiences to recognise which were the Japanese fighters and which were the bombers.
But then there are those instances where historical liberties in films are not so harmless. One example is the recent Japanese WW2 film 'To Those We Love' (2007) which is about a squadron of Army Kamikaze Pilots in 1945. A scene depicting a group of senior Japanese commanders planning an attack has one officer lamenting sadly on the looming defeat of his nation, "
We only wished to make the Pacific free for all Asian Peoples"..... Anyone with a any degree of knowledge on the Pacific war must know what a self-serving, fact-distorting historical furphy that line of dialogue was, given that the numbers of people of South-East Asia who perished under Japanese occupation ran into the millions. Yet, many young Japanese would see that movie and such scenes would reinforce the distorted view that many have of their nation's role in WW2, namely the view that Japan was the mis-understood victim of American aggression and imperialism.
That is the big issue with war films, there is always the struggle between truth and entertainment and often the two do not see eye-to-eye.
