Truth about Jason Isaacs full-frontal nude scene on The White Lotus revealed

The White Lotus stars have spilled on that explicit Jason Isaacs nude scene where he exposed himself on camera.

Setting the record erect.

Jason Isaacs did not expose his real private parts in that The White Lotus Season 3 full-frontal scene.

“That wasn’t his real penis,” Sam Nivola, who plays one of Isaacs’ on-screen sons, told TV Insider in an interview alongside his on-screen sister, Sarah Catherine Hook.

Hook confirmed that “it was a prosthetic,” though she admittedly “blacked out” during the scene in question.

Isaacs, however, was “so excited to do it” and maybe even “took pride” in the steamy display, the actress revealed.

In fact, Nivola, 21, recalled the actor running around set exclaiming, “It’s my fake d**k scene today!”

Hook, 29, laughed as she added that the scene was “a big deal” to their on-screen dad, who “gave that guy [presumably, the cameraman] a nice shot — several times!”

Nivola agreed, “He sure did!”

Isaacs’ character, Timothy Ratliff — a wealthy but stressed-out businessman on the brink of ruin — bared all in Sunday’s episode of the hit HBO series.

Ratliff popped a few prescription pills before joining his on-screen children, which include Patrick Schwarzenegger.

A loopy Ratliff, who was wearing nothing but a robe, then sat on a chair and ended up flashing his fictional family — and millions of viewers.

“Yeah, it is now in my contract for every show I do, so we’ll see,” the 61-year-old later quipped to Entertainment Weekly, adding, “It’ll get easier, hopefully.”

Schwarzenegger, 31 — who had his own nude scene in the Season 3 premiere — jokingly interjected, “You should be asking what it was like for us to watch it!”

Isaacs teased that the viral moment is just the beginning of Ratliff’s downward spiral — a task he described as “challenging.”

“I remember reading the scripts thinking, ‘Wow, I’ve got to keep my powder dry for five or six episodes and then this s**t really kicks off,’” the Harry Potter star said.

“I just remember thinking, ‘I better dig deep and produce something here,’” he continued, dishing that “there’s some big, old acting coming up.”

Despite fully immersing himself in Ratliff’s development, Isaacs doesn’t “know how [he] pulled it off” because he had to “access” a certain level of “mania and a terror” — all while replacing his English accent with a Southern one.
