Night Must Fall is a 1964 British film directed by Karel Reisz and starring Albert Finney, Mona Washbourne and Susan Hampshire.

The man, later shown to be a hotel bellboy named Danny, is summoned to the home of Mrs. Bramson, a wealthy widow, whose maid, Dora, is pregnant by him.

Having charmed Mrs. Bramson, he is soon living in her house and pretends to be her son, while redecorating a room and assuming butler duties.

[3] 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. ...

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.
