Jude Law says The New Pope had me wear the "smallest costume I was ever given": A napkin

Deadline

“You’d be surprised to know those swimming trunks weren’t the smallest costume,” the actor laughed to Deadline. “I asked the costumier, one day, what I would be wearing, and he lifted up a tiny piece of material. I have a photo of it because it was truly the smallest costume I have ever been given," which was a single napkin. Creator Paolo Sorrentino adds jokingly of the nudity in the The Young Pope follow-up: "You’ve only seen two episodes, the nudity is very well distributed throughout the series. There is a lot of equality in the nudity, often women and men. And, of course, animals.”
