110 hours of aerial footage was shot for Battle of Britain (1969), of which only 40 minutes appeared in the film. The unused footage still shows up regularly in TV Shows and movies about the period because today it costs more than $10,000 an hour to rent a real Spitfire for a film, so licensing the footage is usually much cheaper. Also, the production had 32 flying German Heinkel 111 bombers to play with (on loan from the Spanish Air Force at the time), but today there are none - The one featured in Dunkirk (2017) was a scale model. Here is a list of films and TV Shows (that I know of) which used some of the footage shot in the summer of '68 for Battle of Britain - but there are probably more!
