‘He Walked by Night’ is a slow burn procedural, perhaps even a little too slow at times
He Walked by Night can lumped into a very special category of film noir. As elaborated in their simply title book, Film Noir (Alain Silver, James Ursini, Film Noir, Taschen, 2004), there exists a sub-movement within noir recognized as docu-noir, wherein the filmmakers go about telling stories based on real life events (as well have German expressionism marry Italian neo-realism, but that is another discussion for another article)
