An excellent subject! I first read "Fly For Your Life" at about the age of seven or eight, shortly after seeing the Battle of Britain Film and recently sought out a copy to add to the library. A superb book.
Tuck also flew Gauntlets and Gladiators before the war - there are two Gladiators flying in the UK (and another on the way I believe) and a Gauntlet in Finland (with P&W engine I think).
And I think there are three or four Mk1 Spits being rebuilt to fly in the UK, including the one Peter Cazenove force landed on a beach near Dunkirk whilst on 92 Sqn with Tuck when first they went into battle.
He111s and Dorniers would be a bit tricky to find these days - no more Spanish sources to tap. I hope the CGI company can reign in their enthusiasm a little and slow the pace of the animations to something rather more realistic than Pearl Harbour!
Good luck and look forward to seeing it.
