10 Cloverfield Lane is one of this year’s more mysterious movies, having been announced only a few weeks ago. The first trailer suggested it was a monster movie, and the newest TV spot all but confirms that… kind of. We don’t actually get a look at any monsters, but there’s a nice howl at the end, along with some really terrified humans. I think this is a great case of less is more when it comes to marketing.

10 Cloverfield Lane hits theaters on March 11.
