Hmmmm, I'm sure there's a few British deathbed moments out there in our classic films.
A sort of dying moment that left me near to tears and feeling very British was at the end of The First of The Few, where Niven flies his Spitfire over a dying Leslie Howard as he watches the sky. I think there's a narration by Howard, which is akin to his lasts words in a way. One of the powerful moments of British cinema.
There must be loads out there.
Odd Man Out - doesn't Mason have a dying speech before he hits the snow? That also nearlly left me in tears. Christ, these classic films knew how to work their audience.
