Some of you know Ender's Game the book; many more of you, I suspect, know Ender's Game the homophobic author controversy. I realize, however, that there are many of you simply unaware of the property at all, beyond it being a movie that's coming. This exhibit may give you a sense of it.
On a superficial level, Ender's Game has a lot of the same plot points as Harry Potter - an existential threat was defeated a generation ago, but there's a good chance it'll be back, so young children are prescreened early on to test their aptitude for battle, then trained in space to be ready for a presumed imminent threat.
The existential threat are aliens who were called "Buggers" in the first book; what's doubly hilarious given Orson Scott Card's personal obsessions is that he claims he didn't know the word already had a sexual meaning, and it was changed in subsequent books to "Formics."

Here's a study room where they get briefed.
This is the video playing on the big screen:
