 "The New York Times" described the film as "a garrulous but occasionally interesting excursion into murder and unrequited love...the script...is basically a static affair that rarely escapes from its sets or the scenarist's verbosity.Suspense is only fitfully generated and then quickly dissipated...Gary Merrill contributes a thoroughly seasoned and convincing portrayal...Emlyn Williams adds a professionally polished characterization...and Anthony Steel and Barbara Murray are adequate...However, "Another Man's Poison" is strictly Bette Davis' meat.She is permitted a wide latitude of histrionics in delineating the designing neurotic who is as flinty a killer as any we've seen in the recent past."
