Many elements of modern horror movies and TV shows came from an unlikely source, a theater in Paris called The Grand Guignol. Beginning in the late 19th century, The Grand Guignol was inventing staples of the horror genre as they discovered how to scare audiences, and why people want to be scared. I talk with University of East Anglia professor and author Richard Hand and Wagner College professor Felicia Ruff about how we can trace the lineage of Psycho, American Horror Story and Sweeney Todd back to The Grand Guignol. Plus, Alex Zavistovich of the Molotov Theatre Group describes what it’s like to recreate Grand Guignol plays for a modern American audience.
