When talk of that film first came out a while ago, Tom Cruise was supposed to star in it.
If you were to do it right, there is a story that would be an interesting one to tell. There were 4 RAF pilots who first met during the Winter Olympics of 37-38 where they all competed. Billy Fiske, Roger Bushnell (Great Escape) Willie Rhoades Moorehouse (KIA BoB) and Max Aitken
To somehow follow their lives from the test of the Olympics to the horror of war, would in my mind make for an interesting story and it wouldn't just be about the American. Moorehouse was the son of a KIA VC winner in World War I. Growing up with that to live up to must have been hard. Bushnell's story is well known enough as the mastermind behind the Great Escape. He'd gone down in a Spitfire over Dunkirk as CO of 92 Squadron.
All 4 served in 601 Squadron RAF, unofficially known as "The Millionaire's Squadron"
It goes on and on. Of the 4, only Max Aitkin survived the war.
