Hammer Films’ exploration into psychological horror, Fear in the Night, proves more entertaining than truly scary. The story centers on Judy Geeson as a woman who has recently experienced a breakdown and relocates with her husband to a school for boys. There, she seems to be targeted by a man possessing an artificial arm, though her claims are dismissed by others. Peter Cushing, Ralph Bates, and Joan Collins feature in the cast, and this film could easily be considered among the least impressive of Hammer’s psychological series. The feeling that it's a low-budget imitation of Hammer’s excellent “Taste of Fear” from 1961 doesn’t help matters; that earlier movie successfully lived up to its potential. Fear in the Night begins with an initially unsettling scenario, and the arrival of Geeson and Bates at the school seemed full of possibilities for suspense and subtle scares. However, the idea of Geeson being threatened within a story largely involving just four characters quickly loses its impact—and Cushing’s talent is noticeably wasted. The film's atmosphere is decent; director and co-writer Jimmy Sangster consistently demonstrated skill in creating an unsettling feeling. The small cast does their best to elevate the limited scope of the project. Ultimately, though, it comes across as a minor distraction that pays tribute to superior films within its genre rather than establishing something new on its own. It earns a 5/10 rating.
