Jude Law put blood, sweat and…poop…into his latest role.

Law, 50, plays King Henry VIII in “Firebrand,” a historical drama that follows the marriage of the king and Queen Catherine Parr, his sixth and final wife — played by Alicia Vikander.

In order to get into the role, the actor had a repulsive perfume blended from “blood, fecal matter and sweat” specially made to wear while shooting the movie.

“I read several interesting accounts that you could smell Henry three rooms away. His leg was rotting so badly. He hid it with rose oil,” Law said at a press conference Monday at Cannes Film Festival, according to Variety. “I thought it would have a great impact if I smelt awful.”

The king infamously suffered from a leg ulcer following a jousting accident that he suffered with for the remainder of his life, and Law went to a perfume specialist to create the nasty smell for him.

“She makes wonderful scents, and she also makes awful scents. She somehow came up with this extraordinary variety of blood, fecal matter and sweat,” he shared.

Law started off lightly applying the perfume, but as filming went on, it became a “spray fest.”

“When he walked in on set it was just horrible,” director Karim Aïnouz admitted.

Though Law plays a monarch in the period drama, he doesn’t care much for the crown — and even laughed when a journalist asked him for his thoughts on the royal family.

“I kind of see it like theater, although I’m slightly more obsessed by theater,” Law shared. “But I’m not one for gossip. I don’t really enjoy it. I find no interest in it, and I don’t really enjoy following tittle-tattle stories.”

However, he did have thoughts on the coronation of King Charles III, adding: “There was something remarkable about looking at the photos of this medieval ceremony and how it applied to today made me feel very modern.”

“Firebrand” — adapted from the 2013 novel “Queen’s Gambit” — had its premiere at the Cannes Film Festival this weekend and was met with an eight-minute standing ovation.
