I have just watched this film. It's black and white, of course. The one with William Holden in it, though I don't think there are any other versions of Sunset Boulevard. I must say how it creeped me out. The house does indeed look like the house from Great Expectations, and Norma Desmond looks like a living spectre! It's something about her eyes, the way they widen crazily. And the butler is so stiff and mechanical it's sometimes hard to believe he's a human being.
The whole thing was quite menacing, though, and I couldn't sleep after I watched it in the dark, too. Strangely enough, my friend, who was watching with me, didn't seem frightened by it at all. How could she not be?
