Robert Day · 1958
Corridors of Blood (1958) is a British horror-drama starring Boris Karloff as Dr. Thomas Bolton, an 1840s surgeon whose pioneering work with anaesthetic gases leads to professional ruin, addiction, and entanglement with criminals. Directed by Robert Day and shot by Geoffrey Faithfull, it trades gothic excess for moral austerity, using tight framing, chiaroscuro lighting, and Karloff’s restrained performance to trace a downward spiral rooted in cause and effect. Though hampered by repetitive plotting and thin characterisation in places, it remains a coherent, atmospheric study of scientific vocation undone by human frailty.
