This was the first feature film directed by Ben Affleck that wasn't nominated for any Academy Awards.
The original cut ran closer to three hours, and was intended to be a very character heavy film.
Robert Richardson wanted to shoot the film with the Ultra Panavision 70 anamorphic lenses he had recently used on Les huit enragés (2015), but Panavision had already rented them for use on Rogue One: Une histoire de Star Wars (2016).
This movie holds the record for the biggest drop in theater count. For its first two weeks of wide release, it played in 2,822 theaters in the U.S. and Canada. On the third week, only 163 theaters were showing it.
