1941's The Wolf Man endures as a masterpiece of the classichorror films, but this deeply felt work also offers a unique insight into the complex psychology of its lead actor. Lon Chaney Jr. rarely opened up in interviews and, when he did, the information he provided about himself was vague and contradictory. This was perhaps intentional; like the character he played in The Wolf Man, Chaney had a monstrous side that he did his best to keep hidden.

Pop culture writer, humorist, and horror cinephile Philip J Reed analyzes the iconic film, using it and a collection of interviews, press materials, and biographical sources as a basis for discovering who Chaney really was when the cameras turned off and night fell. Chaney's work on screen provides valuable insight into his real-life struggles with alcoholism, violence, depression, and a tortured relationship with his celebrated, even more monstrous father.

The Wolf Man is an effective work of lingering horror. The story of its lead actor might be even more haunting.
