Sinners is based on actual persons and events. The real "Troy" is serving a life sentence without possibility of parole.
The clock on the wall in Troy's interrogation room starts at 11:11, a tribute to the production company, Eleven Eleven Pictures.
The cast and crew achieved a personal best by shooting 16 scenes in one night, but the camera failed and all 16 scenes had to be re-shot.
Troy's inmate number on death row is 12261, the director's date of birth.
Kodiak, the dog playing Diogee, was the only cast member to film on location outside of California.
