Jason Isaacs 'White Lotus' Secret Exposed by his Onscreen Children

As it turns out, actor Jason Isaacs did wear a prosthetic in his full-frontal scene on last Sunday's episode of "The White Lotus." The actor joked about earlier this week, telling Entertainment Weekly "Yeah, it is now in my contract for every show I do, so we'll see. It'll get easier, hopefully."

What he didn't say was whether he was wearing a prosthetic, but two of the young actors who play his children did in an interview with TV Insider.

"That wasn't his real penis," confirms Sam Nivola, who plays Lochlan, the earnest son of Issacs' character, the increasingly troubled Timothy Ratliff. The businessman dad had been self-medicating with his wife Victoria's (Parker Posey) Lorazepam and was so doped up in the morning that he carelessly let his robe fall open, inadvertently exposing the family to his jewels."

"It was a prosthetic," co-star Sarah Catherine Hook, who plays his older sister Piper, concurred. In the scene, Piper covered her eyes, Lochlan winced, and the third sibling, Alpha-bro Saxon (Patrick Schwarzenegger), laughed along with his mom Victoria (Parker Posey). Schwarzenegger famously showed off his butt and penis in the show's opening episode.

"It was really funny. He was very excited to do it. I think he took pride in the prosthetic," Hook says of Isaacs with a laugh.

"He's like, 'It's my fake dick scene today!'" Nivola says.

Isaacs joined the exclusive "White Lotus" Dick Club, which also includes Steve Zahn on Season 1 and hunky Theo James on Season 2. Whether more characters will be joining it this season remains to be seen, but rumors are things heat up with the Ratliff boys on the two upcoming episodes.
