Public Enemies

On two different occasions, the film utilizes stock footage of exteriors for establishing shots. The first: When Arthur Dunlop (Eric Roberts) is drinking in the bar and spills info on the kidnapping, the exterior shows it to be the "Pitty Pat Club" which was featured in the movie "Harlem Nights". Second: When Melvin Purvis finds Arthur "Dock" Barker (James Marsden) and arrests him, the exterior shot shows a street corner building beneath some elevated tracks with a curved corner. This exterior is from "The Untouchables" (1987). It was in the scene where the little girl goes into the saloon before it blows up.

The final shootout between Ma Barker and Melvin Purvis is captioned to have occurred in Lake "Wier" when in fact the location is near Lake Weir.

In the suicide scene, it was originally written that Herman Barker's whole head would explode, but director, Mark L. Lester, decided it was too gory for just one scene, and changed it to the back of his neck exploding instead.
