I was first introduced to Peter Medak's 1980 film "The Changeling" for the first time earlier this year. I've since watched it again, and come to really love its quiet build-up and classic 'dark old house' tale about a man (George C. Scott) who rents an old mansion and becomes embroiled in bumps in the night, scary child noises and a seance. Medak, a director who dabbles in several genres, clearly understands how effective the edges of the frame can be. And silence... which makes the loud bumps and shakes all the more impressive when they do resonate. All around, "The Changeling" is a fascinating and scary horror whodunit.
The highlight has to be the aforementioned seance scene, which pretty much wrote the book on filming these types of things, including first showing the phenomenon known as automatic writing. If you haven't already seen it, rush on over and send it to the top of your Netflix queue now.
