Honestly, I never could figure any of them out and would tend to agree with singi. Trying to explain them is like trying to describe a dream- they're just all over the place! I am a visually-oriented person and Lynch's use of tableaux and other design elements on his sets always thrills me. I remember a scene in Twin Peaks where there were three guys all dressed alike and posed the same way in the background of a bar scene for no apparent reason, almost just to see if you'd notice.
Oh, DaveL, I loved the midget! He was in the Julee Cruise video, too, as the narrator. The whole thing was about broken hearts and hearing it come from the small guy seemed to illustrate how small a broken-hearted person feels. I guess that's kind of trite, but Lynch seems to like that sort of corny emotional thing played with a bizarre twist. One of Lynch's pieces from the video, "I'm Hurt Bad", is played on the juke box in the first Twin Peaks episode.

).. Blue Velvet is in my top ten favorite films of all time, and The Elephant Man almost made me cry.. I haven't seen Dune, Twin Peaks, and Eraserhead yet though.. Oh and Mulholland Dr. is one of the best movies of this decade.
