Marriage was split over a few years but the bulk of the shoot was done in a 6 week block one winter in 2012. This is a documentary that was produced with behind the scenes and interviews. After this was shot work started on visual effects, editing and during that phase a number of other scenes were added away from the location here. This was always part of the plan - one of the main reasons we didn't hire cameras at the time but bought in what we needed.
Notice at the time this was the shot the branding for the film was vastly different!
