Haunting trailer for Korean chiller The Wailing

If you've managed to avoid South Korean cinema to date, you've been missing out.

The island nation may be small but their movie output is not only prolific, it's also of consistently high quality. Heart wrenching dramas, taut thrillers and utterly insane action films spill out of their borders every year. And that's before we mention the bone chilling horror entries.

The latest effort getting some serious attention is The Wailing. It's a new film by Na Hong-jin, who previously helmed the breathless crime thriller The Yellow Sea. And this one is supposed to be truly terrifying.
