A 1942 British war propaganda film, well worth the time to view it.
Directed by (and starring) Leslie Howard, who was killed one year later in a DC-3 shot down over the Bay of Biscay by a Junkers JU 88CS.
According to IMDB:
In the film Leslie Howard's Mitchell says he wants his new fighter to be "a bird that breathes fire and spits out death and destruction; A *spitfire* bird", giving the aircraft its name. In reality, when RJ Mitchell was told the name the RAF had given to his design he is supposed to have said: "That's the sort of bloody silly name they would choose!"
