There's also a brief statement from producer Wyck Godfrey
Catherine has had great success really capturing the lives of young people in particular and the conflict and crisis, and pain of being that age growing up and the idea of her bringing that point of view to biblical times I think is really interesting....which nicely sums up some of the thematic elements, and I suppose why they were attracted to her as a director. Certainly the way she has captured adolescent life elsewhere is what makes this project about a teenage Mary most interesting.
Whilst the featurette doesn't really say too much, you get a bit of a feel for the look of the film. One thing, in particular, that does stand out is Keisha Castle-Hughes as Mary who looks impressive even in the brief glances we see here.
