HBO's coming battle on "Game of Thrones" is expected to be an enormous, record-breaking episode of television. The cast and crew spent weeks and weeks shooting the sequence, and were exhausted and worn-down after not seeing the sun for "almost three months."

Thanks to teaser videos, released photos, and set interviews, we know a fair amount about what may come during Sunday's bloodbath.

Keep reading for a look at the 19 things you should know about the Battle of Winterfell.

Let's start with the basics. Season eight, episode three (title unknown) will be 82 minutes long.

With that runtime, the Battle of Winterfell episode will be the longest in "Game of Thrones" history. The last episode to hold that record was the seventh season finale, "The Dragon and the Wolf," which was 79 minutes.

According to a report from Entertainment Weekly's James Hibberd, this episode will also contain "the longest consecutive battle sequence" ever seen on TV or in movies. 

The episode was directed by Miguel Sapochnik, who memorably helmed "The Battle of the Bastards" and two other highly rated episodes.

Sapochnik made waves among "Game of Thrones" fans when he directed the bombshell season five episode "Hardhome," on which Jon Snow faced the Night King for the first time.

Then, in addition to the "Battle of the Bastards" episode, he directed that season's indelible finale, "The Winds of Winter" (the episode on which Cersei blew up the Sept of Baelor).

Now let's take a closer look at Daenerys and Jon's battle strategy.

In both the teaser trailer and released photos for the Battle of Winterfell episode, Daenerys and Jon are shown on what looks like a cliff overlooking Winterfell.

Since the troops are still in line, this is pre-fight. Maybe Daenerys and Jon each rode a dragon to do a scouting run before the battle starts?
