I am shocked to find Three Godfathers and the Shining in your worst list big poppa.  For Ford I would probably pick Stagecoach, which is a waste of time and space, although it still might not be his worst.  The Lady Vanishes is the worst of Hitchcock, although "gasp" Vertigo is a close second.  Raiders of the Lost Ark from Speilberg.  The White Sheik from Fellini, Sgt. York from Hawks, My Fair Lady from Cukor, and To Be or Not To Be from Lubitsch.  I know many people are turning into the incredible Hulk reading this, but I feel the same way about your constant Fellini and Bergman bashing.
