The Monthly Film Bulletin wrote: "The opening shots with the girl on the swing, the sunlit trees, the darker recesses of the forest, the crescendo of alarm signals on the soundtrack, and the psychopath, stripped to the waist, hacking away at his victim in the undergrowth, give a very fair indication of the sort of film that this is going to be: not so much a thriller as a typically humourless example of that overworked genre known as psychological drama. ... Perhaps the most depressing thing about the film, however, is that nowhere can one spot the director's reason for making it. Sad to reflect that Karel Reisz has taken over three years to follow up the success of
Saturday Night and Sunday Morning with something as flawed as this." However, Paul Mavis, reviewing the Warner Archive DVD release for Movies & Drinks, wrote, "Taking Emlyn Williams’s old chestnut and transforming it into a startlingly off-putting psychological shocker, director Karl Reisz’s and Albert Finney’s “Angry Young Psychopath”
Night Must Fall has more on its mind than the non-existent gore that some critics insisted was there, making the charmingly jumped-up killer terrifyingly opaque…while dissecting the all-too-readable victims. It’s an intense, sustained vision of inexplicable, murderous frustration." ==References==
