“Sometimes your body doesn’t know it’s not real,” he explains.

Groff ultimately decided not to rehearse it too much before the time came.

He would go to set on the day and do the scene.

“When it was over, I was like, ‘I think I wet my pants.

I think I peed myself,'” he admits.

“You know when you pee yourself you feel that, like, hot urine?

But then, it didn’t go away,” he continues as his castmates burst into laughs.

Groff was determined to solve this mystery.

I was reaching down there looking for this shell but it wasn’t down there.

“Groin,” he finishes with a smile.

“You were saying sometimes your body doesn’t know it’s not real,” Groff recalls.

“Unless you’re really experienced [and] you’ve gone beyond that point.

My body has a physical reaction to it.”

“But you didn’t pee your pants,” she clarifies of Groff.

“To be clear.”

Groff surprised even himself.

It was more than just re-watching the originalMatrixmovies to get into character.

“I was trying to osmosis the original stuff as much as I could,” he says.

Though, he confirms that behind the ferocity was still glimmers of Groff’s infectious personality.

“Like, you’d drop the serious face just to show some excitement.

Then you’d get back into the zone.

I was like, ‘God, the boy is working!'”
