'Game of Thrones' prequel pilot begins filming in Northern Ireland

The first prequel series set in the lands of Westeros has quietly begun production.

Jason Momoa left little to the imagination during his Wednesday night appearance on "Jimmy Kimmel Live."

During the segment, Kimmel, 54, displayed an Instagram photo the 43-year-old actor recently posted that showed him wearing a beige loincloth while on a fishing trip.

"I want to ask you about this photograph, because this is, I assume, happens in Hawaii. You're deep sea fishing there. None of the other guys are wearing one of these," Kimmel said to laughter from the audience.

"That's a malo. It's what the Hawaiians wear," Momoa explained.

"I'm doing a show. I'm a creator and writer and director and producer on this Apple series called "Chief of War," and it's all 1780s, 1790s Hawaii.

He told Kimmel he found his "Chief of War" character's malo costume very comfortable.

"I actually don't even like wearing clothes anymore," Momoa said. "I'm in it every day. I wear it all the time."

"Are you wearing this, like, under your clothes right now?" Kimmel asked.

"Of course," Momoa replied.

Kimmel responded, "Are you really? Is it made out of leather? I'm having a hard time figuring out what it's uh …"

Momoa then stood up and took off his jacket as the audience cheered. He peeled off his shirt and pulled down his pajama pants to reveal the malo.

The Hawaii native turned around in a circle to give the audience and Kimmel a full view of his bare backside. He then turned to the side and did a jiggle while the audience applauded.
