Los Angeles artist and special effects virtuoso Pat O’Neill filmed The Decay of Fiction (2002) in the landmark Ambassador Hotel, once the center of Hollywood celebrity culture. His film blurs the boundaries between architectural investigation, urban documentation, and aesthetic exploration. At once a poetic homage to classical film genres, it is also a suggestive indication of how remembering the city is changing in response to new technologies.
