Well as I may have mentioned before once or twice, for me it's got to be
A Matter of Life and Death (1946) [AKA
Stairway to Heaven]. I've seen it countless times, on TV and many, many times on the big screen. I know a heck of a lot about it, but it still has the power to move me to tears every time I see it.
It just hits all the right buttons for me. It's wonderfully romantic, but it also covers philosophy, history, religion and many other areas of great interest to me.
Made by The Archers who were not just Powell and Pressburger but also Jack Cardiff, Alfred Junge, Hein Heckroth and many others in a team. Most of whom had been working together for some years and were at the top of their game at this period.
It's got some stunning special effects that are still hard to match in these days of CGI. But they don't make the effects stand out. No big, flame filled explosions here. Some of the best special effects are so naturalistic they're almost unnoticable.
If I was to pick just one aspect of it that makes it stand out from other films, I'd probably pick just the sheer audacity in making a film about life and death so soon after a war where millions had died.
And there's so much depth to it that even someone who has studied everything ever written about it and just about every frame of it can still find more in it. And some of the detail must have taken them weeks to research and put together, yet like the special effects, they're not obvious. They just go to make it all the more realistic - which is odd for a film that is usually classified as a fantasy.
And despite all of that complexity, it is still easily accessible. It leaves a wonderful impression on first viewing. It's often when people realise that it was made so long ago, back in 1945/6 that they express the most surprise.
