Leah Jeffries, Charlie Bushnell, and director James Bobin tease the Disney+ adaptation’s epic game.
What Quidditch is forHarry Potter, Capture the Flag is forPercy Jackson and the Olympians.
For years, book readers have played their own versions of demigod Capture the Flag.

The first step, of course, was building Camp Half-Blood.
And so some are stone, some are wood, and some are different shapes.
I wanted to build a place that when you watched the show, you wanted to go there.

Once Camp Half-Blood was built, it was time to play.
It was so much fun.
It was like my dream come true.
Thats not to say it was easy, though.
Leah Jeffries, who plays Percys friend Annabeth Chase, had a particularly harrowing experience on the big day.
As the daughter of the wisdom goddess Athena, Annabeth is usually unflappable.
But while Jeffries was playing it cool during Capture the Flag, she got struck by a creepy-crawly surprise.
That day it was so hot and I had all that dark armor on me.
I was dying, Jeffries recalls, to the shock of her costars.
And then on top of that, a spider actually crawled up inside of my armor.
It literally looked like a poisonous spider.
It was big and black.
I was about to cry.
That was really bad.
Other participants had a happier time, thankfully.
My son’s birthday was on the day we were shooting, Bobin says.
The props guy said to me, You know what?
I’ve never seen him so happy.
