"Horror film aficionados have long known about an underrated, little-recognized gem from the early '60s called Horror Hotel. Due to its low budget, The City of the Dead was completely filmed on a sound stage. No scenes were filmed outside. However, instead of becoming a liability, this limitation actually works in the film's favor, giving it a strong sense of claustrophobia, which makes the horror all the more palpable... One of the movie's greatest virtues is its sense of a secluded other-worldly environment of near-Lovecraftian implications." - Gary Johnson, Images Journal
