Nell Forbes was by far the darkest and most volatile character Marilyn Monroe had ever portrayed in her entire career. Written by Daniel Taradash and directed by Roy Ward Baker, Don't Bother To Knock - a chilling and uncommonly masterful film noir thriller - gives its viewers an up-close glimpse into the crevices of a deeply disturbed human soul. Need a babysitter ... anyone? Yet another five star oeuvre, Don't Bother To Knock is an effort of prodigious degree in classic cinema.
