The first trailer for Mud director Jeff Nicholsā€™ Midnight Special was all about a sci-fi mystery, with Michael Shannon running across the country alongside Joel Edgerton and a magic little boy who has supernatural powers of some kind. This new trailer expands on the first one a little, mostly in the form of more interactions between Shannon and the magic boy, who happens to be his son. Thereā€™s still a lot of mysterious stuff happening, and some bad-looking military dudes are still out to get the magic boy, but it seems like Michael Shannon is going to do whatever it takes to protect his son (like using a thick accent that involves not moving his mouth a whole lot). Near the end of the trailer, Shannon tells his son that heā€™ll always worry about him, and that he likes worrying about him, indicating that he loves the boy despite his glowing eyes and magic powers. Thereā€™s probably a lesson in that for any dads out there.

Midnight Special will be in theaters on March 18.
