I received my copy of the FNE 4th Edition last week. I was anxious to see what had been changed since the 1993 publication of the 3rd edition. They do seem to have addressed the plot synopses errors from previous edtions.
When I study the FNE 4th titles, they have now included some sci-fi titles - not sure how noir they really are: THE DAY THE EARTH STOOD STILL (1951), INVADERS FROM MARS (1953), THEM! (1954) + INVASION OF THE BODY SNATCHERS (1956) which was listed by Keaney (Film Noir Guide, 2003) & Selby (Dark City: The Film Noir, 2004). They have also added a number of westerns which had previously only been listed by Keaney: THE OX-BOW INCIDENT (1943), JOHNNY GUITAR (19540, RANCHO NOTORIOUS (1952), BLOOD ON THE MOON (1948) [also listed by Selby], DEVIL'S DOORWAY (1950) [also listed by Selby], NAKED SPUR (1954) [also listed by Duncan] (Film Noir: Films of Trust & Betrayal, 2003), RAMROD (1947) [also listed by Duncan]. Westerns not previously listed by the referenced sources are: DUEL IN THE SUN (1946) & I SHOT JESSE JAMES 1949). They also added the Ida Lupino directed film THE BIGAMIST (1953) to their list.
I don't have any real problem with these new titles, but I was very surprised at some that they dropped, such as MINISTRY OF FEAR (1944), THE TATTOOED STRANGER (1950), BLACK TUESDAY (1954) & THE MANCHURIAN CANDIDATE (1962). Well - maybe I do have a problem - don't understand dropping a film like MINISTRY OF FEAR and then adding some very marginal titles instead.
