the interiors of suspiria

A few days ago I decided to do something else than watching Twin Peaks all day long and decided to watch a movie instead. That's how I rule. I don't want to sit in front of the computer watching Twin Peaks all day long, so I'm sitting in front of the computer and watch a movie.
I watched Suspiria. A horror film from the 70s by the Italian director Dario Argento. I like old horror films quite a lot. I can't stand the new ones, trash like Saw etc. I like these old ones where you only get scared a little and there is a story and everything's so beautiful.
Suspiria is a movie with awkward acting, creepy smiling, amusing stabbing, childlike dialogs, the best soundtrack I've heard in a good while, and the most beautiful colors and interior design ever. I fell in love with the interior design. Take a look and listen to the theme of the movie:

The colors! I love them. And blue velvet walls? I mean, come on, they are awesome, right? ;)

Do you know some good old horror films? Or other movies with amazing interior designs or buildings?
