This slithering Tolkien creation spawned a whole cult of kinky boyfriends who lurked in the shadows and hissed 'My preciousssss' to elicit high-pitched screams.

One of the best parts of the trilogy -- actor Andy Serkis ably supported the fabulous CGI -- Gollum guaranteed that neck skin would, indeed, crawl.

From the film:

Sam: What are you upto? Sneaking off, are we?

Gollum: Sneaking? Sneaking? Fat hobbit is always so polite. Sméagol shows them secret ways that nobody else could find, and they say 'sneak'. Sneak? Very nice friend. Oh yes, my preciousss. Very nice, very nice.

Sam: All right, all right! You just startled me, is all. What were you doing?

[pause]

Gollum: Sneaking.

Shudder.
