A Matter of Life and Death (1946)

AKA in the US "Stairway to Heaven" stars David Niven as a WW II master bomber whose plane is bound to crash, so he bales out without a parachute. Somehow he survives, but it's a mistake. Before the error is noticed in the other realm, he falls in love. When Conductor 71 arrives to take him on, he pleads for a second chance at life with his new love. A trial is set in "heaven" to hear his case. This movie is amazing and weird and wonderful and memorable. Niven is great, as are his costars.
