Plzzz help! i'm trying to find the name of A movie iSaw Only once, as a child, during the 60's! The Lead Actor was very handsome and he had a distinguishing voice! iBelieve it was an old B & W suspenseful, thriller ~ type, movie where the husband try to poison his wife via concocting his own manner of all sorts of sordid bacteria!
