Sid and Nancy/Wuthering Heights (1939/1985) by Jenny Curtis - Crackpot

Here goes: they both end with the main characters as ghosts fading into the distance. In WH Heathcliff's romantic idealism is corrupted by Kathy's worldliness just as Sid's is corrupted by Nancy's heroin in SAN. 

Wuthering Heights the film, bears little resemblance to the book of the same name and should be regarded as a separate entity--in the same way that Sid and Nancy has little to do with the actual guy named Sid Vicious and his girlfriend Nancy Spungeon. 

Sid sings "I Wanna be Your Dog," while Heathcliff declares that "I've stayed here and been beaten like a dog, abused and cursed and driven mad, but I stayed just to be near you, even as a dog." A song on the Sid and Nancy sountrack begs "I wanna be haunted by your ghost," while Heathcliff prays that Kathy will "haunt me--drive me mad." 

Gary Oldman vs. Lawrence Olivier: Oldman's Sid is wild, romantic, stupid, sloppy and on occasion, actually vicious. Olivier's Heathcliff is also wild, romantic, stupid, sloppy and occasionally vicious. They are both doggedly loyal to their last breath to their Nancy and Kathy.  Both Nancy and Kathy attempt suicide, leaving Heathcliff and Sid to take the blame. 

Merle Oberon vs. Cloe Web: Oberon's Kathy is greedy, playful, worldly and irritatingly breathy. Web's Nancy is greedy, playful, worldly and irritatingly whiny. You say tomato... 

Favorite scene 
      (Wuthering Heights) Kathy's tantrum as she tears off a borrowed frock and cries to David Niven, "I hate the look of your milk white face, I hate the touch of your soft foolish hands." 

(Sid and Nancy) Nancy's tantrum in the street where she tears off a borrowed frock, screaming "I look like f**king Stevie Nicks."
