Duvall and the Dogman

After watching The Shining yesterday, I realize that Shelley Duvall was brilliantly pitiful both on and off the set. I really felt bad for her lanky persona throughout. Supposedly she took this part while halfway through a stress breakdown and she is now remembered as this "attention-seeking hypochondriac diva" that neurotic Stanley Kubrick whipped into form. Well Shell, you had me fooled and the Making-Of featurette documenting your breakdowns solidified your role as Wendy Torrance both on and off the set. I would buy you a pack of cigarettes if I saw you on the street.

Another thing:

When Wendy is running alone through the hotel and sees the guy in dog mask giving felash to the creepy older man. What is going on here and why is it traumatic, you ask? Upon further fanboy research, I have discovered (thanks to the IMDb messageboard topic):

1. According to King's novel, the man in the tuxedo is a multimillionaire playboy by the name of Harry Derwent and the figure in the dog suit is his male lover.
2. The scene highlights the power structures of the hotel.
3. The scene neatly encapsulates all the film's themes of victimization, dominance, subservience and duty. 
4. Being as it is Wendy who witnesses the scene, the scene seems to highlight her subconscious fears. IE- sex without women (Jack no longer sees her as a "sperm bank". She no longer registers as his "duty" to please).
5. "Get it up!" the drunken dogman cried out from around the corner. His voice was both violent and despairing. "Get it up, Harry you bitch-bastard! I don't care how many casinos and airlines and movie companies you own! I know what you like in the privacy of your own h-home! Get it up! I'll huff... and I'll puff ... until Harry Derwent's all bloowwwwn down!" He ended with a long, chilling howl that seemed to turn into a scream of rage and pain just before it dwindled off. (page 228, chapter 41 "Daylight")The fact that Jack is the one that says this line in the movie is very important. It's quite an obvious clue to a major reversal that Stanley Kubrick made to Stephen King's novel.
