Trivia

Part of this movie was filmed in an abandoned prison in Gloucester, UK

When the movie was first announced, Josh Brolin, Maggie Gyllenhaal, Olivia Munn, David Oyelowo and Luke Evans were cast in the lead roles.

Filming took place at Bethesda Terrace and Fountain in Central Park, New York

This is Joel Kinnaman and Common third feature film collaboration, after Run All Night (2015) and Suicide Squad (2016) (although they don't share any scenes in that film).

Tattoo on the chest of main character which is clearly seen when being taken into prison translates to: Before you fell, you crossed the ground with your hand. Was it a bullet, my boy, or was it the heart that broke?

This excerpt is from the poem "Elegy for a Polish Boy" ("Elegia o chlopcu polskim") by Krzysztof Kamil Baczynski. The poem reflects on the tragic fate of a young boy who fought for his homeland during World War II. The uncertainty of whether it was a bullet or a broken heart adds to the emotional weight of the verse. Polish people tend to embrace tragic history of their country.
