Old Movie Title

[kateallie]

does anyone know the name of a very old movie set in the mountains, maybe around Japan, where there's a secret valley. if the people stayed in the valley they didn't age but when they left they immediately became their true age. i think the main guy recovered from a plane wreck and fell in love with a beautiful asian woman who followed him out and died when she aged

I think it may have been a Frank Capra film Lost Horizon
