I haven't seen the Hitchcock original, although I have seen the 50's version Man in the Attic, starring Jack Palance, a film I liked. This 40's version of the novel is an equally fine movie, with an entertainingly creepy lead performance by Laird Cregar in the role as the lodger (Jack the bloomin' Ripper to you and me). The foggy London streets create nice atmosphere and the support cast all also contribute nicely. All-in-all, a quality production.
