This point has been raised before, but I think it bears repeating. Besides that, it's nice to vent a little spleen now and again!
This film will be severely criticized, and rightfully so. Much of the criticism will be due to the potpourri of fact and fantasy in the story line. Given a decision to craft a story about actual historical figures, some fidelity to the truth of these people's lives should be maintained. If a person's life story is too dreary and uninteresting to be the basis of a film, why not seek out more promising subjects? Surely this would be preferable to weaving a web of deliberate lies that might take years to untangle.
If the story a film producer wants to tell doesn't match up with the actual historical figure chosen to be the leading player in that story, the obvious fix is to create a fictitious character who can conform to the demands of the story, whatever they may be. It is a pity this approach was not taken with
The Red Baron. The aircraft photo mock-ups look very good, and show at lot of attention to detail. So long as the flight dynamics models chosen for the computer graphics are not more appropriate for an F-15 than an Albatros D.III, some very nice flight sequences should be possible.
Failing even in this, it may yet be possible to salvage something from the film. All that is necessary is to incorporate a small beagle in flying kit, zooming across the screen on his faithful Sopwith doghouse from time to time, howling curses at the film's namesake.
