If you have access to the US Netflix, I recommend giving This is Martin Bonner a watch (it's only going to be up for another day or two). It's a film about a man who works for a Christian organisation that aids former prisoners in their emergence back into society. It's also one of the only films I've ever seen whose main character has a degree in theology! At just over 80 minutes it is a short watch, but I am still mulling over its contents.
And it's got Karl Barth in it.
