I just came across this, a PoW movie with a 'true story' tag
"Treats the PoW experience seriously" it says on the box... well I'll let you know
Edit: What a great movie... it's just wonderful! Impeccable production, performances, acting, direction and music... not least the music. I was anticipating at best a capable/bearable PoW yarn with amateur performances and rickety sets... but this just knocked me out completely. A totally magical and immersive film
