5 things you didn't know about the crazy twist ending of '10 Cloverfield Lane'

One of the surprise hits of 2016 has been "10 Cloverfield Lane," the "spiritual sequel" to the 2008 found-footage movie "Cloverfield," which followed a group of New Yorkers during an alien attack.

In "Lane," producer J.J. Abrams (also behind the original) and director Daniel Trachtenberg create a story that has the feel of a thrilling sci-fi movie, but for different reasons than "Cloverfield."

In this story, we follow Michelle (Mary Elizabeth Winstead) after she has been in a car accident. She's now in an underground bunker being taken care of by Howard (John Goodman), who informs her that an attack has happened on the planet and that the air outside is no longer breathable.

This leads to a trippy series of mind games and thrills that suggest, as the movie's tagline says, "Monsters come in many forms."

For the movie's Blu-ray/DVD/Digital HD release on Tuesday, Business Insider talked to Trachtenberg about the evolution of its thrilling ending.
