The British actor is playing a fictional pontiff in a new series expected to be screened later this year

Jude Law has appeared in papal robes in Venice on the set of a new TV series.

Law, who plays the part of fictional Pope Pius XIII in The Young Pope, wore a cassock and a zucchetto while filming scenes in St Mark’s Square on Tuesday.

During filming, he stood on a raised platform and spoke into a microphone, in a scene possibly depicting a papal audience.

The series, which is a joint production between HBO, Sky and Canal+, is expected to air later this year.

Directed by the Oscar-winning Italian filmmaker Paolo Sorrentino, the plot reportedly tells the story of Law’s conservative American pontiff clashing with Vatican hierarchy.

Diane Keaton also appears in the series as Sister Mary, one of Pius’s closest aides.

The Young Pope began filming last year with locations including Rome and South Africa. There is expected to be further filming in America and Puerto Rico.

Discussing his papal costume, Law told Hollywood Reporter: “At the moment, it’s that I can only sit on a very uncomfortable sort of stool because they don’t want my papal robes to get creased. So I have to sort of hitch them up and put them over the stool and perch.

“So once I put the robes on, I usually spend the day, 14 hours, whatever, unable to sit. So I look great, but I’m very uncomfortable.”

He added: “The best part of the job is this opportunity to educate yourself and teach yourself and submerge yourself in the world, in the facts, the history, background, skills, whatever it may be, of the character you’re playing.”

Sorrentino, whose latest film Youth will be released in the UK on January 29, said The Young Pope is about “how faith can be searched for and lost”.

“[It shows] the inner struggle between the huge responsibility of the head of the Catholic Church and the miseries of the simple man that fate (or the Holy Spirit) chose as Pontiff,” he said.
