i would really recommend this film. It's called, The boy in the striped pyjamas.

A very emotional film that everyone in my opinion should go and watch it! Let me know what you think about it. It has audio description, and it's probably not expensive now. Amazon will deafly have it. I am not sure about shops, because I don't know when it came out. But any online shops will deafly have it. Have a look!
