The shed Johnny and Emma hide in was originally located behind the barn, but it was discovered during the shoot that the shed had been demolished to make room for removing an old RV.
The character of Emma wasn't in the book by Michael Laimo; she was specifically created for this film.
The set was infested first with ladybugs and then with flies, which hatched from a nearby field. Flies can be seen crawling on actors faces, walls, and props in the second half of the film.
One of the police cars caught on fire while running its lights in the background as Depford is arrested.
