I haven’t seen the film, but I’ve heard its theme track. I’m talking about the film Merry Christmas Mr. Lawrence. The theme is composed by this bloke –>
Dude’s known to the world as Ryuichi Sakamoto. I can’t say much about this theme thing, except that it’s entirely instrumental, really beautiful/calm, and will probably have you going “I’ve heard this before? What’s it from again?”
The answer for me was rather disappointing; it came from a prestiguous warfilm from the 80s I can’t recall seeing. Usually, when I hear a tune I recognize but can’t place I always hope that it’s connected to something that I used to experience or watch (a lot) as a kid and that finding whatever the song is linked to will rekindle fond memories. Not so.
