To cleanse the palate, it looked like a sure thing in December after the first trailer and it looks like a sure thing now. The emphasis on battle scenes in the clip below doesn’t appear to be a tease, either. Unless the film is shorter than everyone expects, the length of the screenplay points to something that’s light on dialogue and heavy on action.

Not many war movies have chronicled a massive retreat, with the trailer beginning, “What has happened is a colossal military disaster,” but this story ends happily, I’m told. And yes, you’ll want to see this in an IMAX theater in case that isn’t obvious. Turns out this is the IMAX-iest movie ever made.
