Well this is a new thing to see on the end of a trailer: “In Theaters and on Netflix October 16.” The world is definitely changing.

Netflix has come a long way from the company that used to send you little red envelopes in the mail. Their original programming slate is expanding exponentially; after making major inroads into television and documentaries, they’re now expanding their feature film division as well. Their ambitious slate of movies includes Beasts of No Nation, the new project from Cary Joji Fukunaga, the director of the first season of True Detective (but not, it should be noted, the second season).

Before Fukunaga garnered massive attention for True Detective, he’d carved out a nice niche in the world of indie film, directing projects like Sin Nombre and 2011’s Jane Eyre. He’s back at it with Beasts of No Nation, which stars Idris Elba from Luther, The Wire, and Mandela: Long Walk to Freedom (and, yes, Thor, you damn Marvel zombies). Here’s the official synopsis:

In a West African country, when civil war tears his family apart and militants kill his father, a young boy named Agu is forced to join a unit of mercenary fighters.

It’s interesting that this “Netflix Original Film” (based on the novel of the same name by Uzodinma Iweala) will debut simultaneously online and in theaters (presumably so it will be eligible for year-end awards and critics-group accolades); theaters remain Netflix’s big competition (and vice versa). The trailer reminds me of the great one for last year’s American Sniper, with a morally conflicted hero faced with an impossible decision that will cost someone their life. What will Agu do? Always smart to end a trailer with a question that the viewer wants answered. You’ve got to seek out the movie to find it.

Beasts of No Nation opens in theaters and debuts on Netflix on October 16.
