So it's true Alicia Silverstone is a woman and a half
Seriously, I was thinking the other day that by far the most "filmic" WWI ace is Mannock. His personality has more sides than the English premier league, and he was also a true "working class hero" who achieved everything he did thanks to his own abilities. Also a socialist and 'anti-establishment' figure, like T.E.Lawrence. Also handsome and charismatic. Plus a tragic and ironic death (he was a flamer just as he had feared).
One scene (probably fictional) that I would want to either open or close with is
Taffy Jones leading an angry meeting of ex-74 Squadron pilots in London, around Christmas 1918. He would remind them of Mick's inspired leadership and demand that they petition for a posthumous VC - which of course he got in summer 1919.
