Ooh. Another one you might check out is Sunset Boulevard. It's an old black & white movie, but well paced (sometimes I find old movies move too slowly). A guy's car breaks down, and the nearest house is that of a rich old silent film star and her butler. He unwittingly becomes her guest/employee/companion/accessory. She's creepy, and the way she hired her butler is even creepier. But her confidence in using him is kind of hot.

Enjoy!
