Oscar Isaac says he slipped the penis-covering 'sock' he used during his 'Dune' nude scene into director Denis Villeneuve's pocket after filming

• Oscar Isaac said he gave Denis Villeneuve his "cock sock" after filming a nude scene for "Dune."
• "Just a little, musty handkerchief," the actor joked on a recent podcast episode.

Oscar Isaac revealed that he gave "Dune" director Denis Villeneuve his "cock sock" after filming a nude scene for the sci-fi epic.

"At one point, when Denis wasn't looking, I may have left my cock sock in his pocket," Isaac said on a recent episode of Entertainment Weekly's Awardist podcast. "Just so he had a little bit of me next to him when I left."

Isaac jokingly called the penis covering — typically used while filming nude scenes on film sets — "a little, musty handkerchief."

The nude scene was the "Scenes from a Marriage" star's final moment in the film. After Isaac's character, Duke Leto Atreides, is captured during an attack on Arrakis, he is stripped naked and brought to the evil Baron Harkonnen (Stellan Skarsgård), who has seized command of the Atreides stronghold.

"Everything about it was just so scary," Isaac said of the pivotal scene, adding that Leto's nudity was carefully considered.

"There was some thought, I think originally, like, 'he doesn't have to be naked,'" Isaac recalled of the decision. "I was like, 'No, he should be naked, man.' It's like Christ on the cross kind of moment. So we came up with a few different ideas of what his posture would be."

The "Star Wars" actor also praised his scene partner Skarsgård.

"Just getting, finally, to have a chance to play with Stellan Skarsgård... was just incredible," Isaac said.

"Dune" stars Timothée Chalamet, Zendaya, Rebecca Ferguson, and Isaac, and also features Javier Bardem, Josh Brolin, and Jason Momoa.
