I am not sure but I believe the finial cut of the film has not been competed …otherwise I would think they would have done as Unbranded did with limited showings to raise the finial money needed to complete the project.
I attended one of the Unbranded showing which had one of the horses there on stage, then afterwards in temporary corral so you could get next to the horse.
(My daughter was at Texas A&M at same time as Ben Masters and they had met)
I believe Billy & Blaze finished the filming almost two years ago, the post production work is what I think has not be completed.
