Sunset Boulevard

I just watched Sunset Boulevard and it is best described as being creepy, creepy, creepy!
I really liked that Buster Keaton and DeMille (yes, the director if "The Ten Commandments") were in the movie but it was creepy that they were credited as themselves (especially heartbreaking as Buster Keaton played another forgotten filmstar who lives in the past- funny to hear his voice though).
The pictures were beautiful, the acting was very good, the music was perfect but the movie was not a nice experience at all.
