not to repeat those above.
The Battle of Britain (133 minutes of stiff upper lip)
(on a similar vein but not quite as awesome
Angels One Five)
Where Eagles Dare (theres even an American in it) "Broadsword to Danny boy...". Put me off cable cars for life.
The Battle for the River Platte, British WWII naval battle, been a long time but it came to mind easily so must have made an impression.
