I noticed in a description of the film, it said that it’s “loosely based” on the the lives of the monks.
What’s ‘loose’ about it?
I don’t know. It seemed pretty accurate to me, from what I knew about them. They lived an authentic Trappist life, although in the Charles de Foucauld mold, that is, trying to convert the Muslims silently, through their charity and witness.
Perhaps it simply means that nobody knows what their last days or hours were like and therefore it can’t be said to be totally historically accurate.
