Harry Potter actor leaves viewers in shock following full frontal nude scene in new season of hit show

An actor who portrayed a prominent villain in the Harry Potter film series flashed his willy in a new season of The White Lotus.

Yep, you read that right.

You can take a look at the trailer for season three below:

The hit HBO show transports viewers to the White Lotus resort in Thailand, where a new group of guests navigate their hidden secrets and complex relationships.

Season three stars Leslie Bibb as Kate Bohrm, Carrie Coon as Laurie Duffy and Michelle Monaghan as Jaclyn, to name a few.

Potter fans, however, will recognise Jason Isaacs taking on the role of businessman Tim Ratliff, who's entangled in a money laundering investigation.

The actor, 61, features throughout the Harry Potter film series as Draco Malfoy's father and Death Eater Lucius.

Jason Isaacs' character accidentally flashes his willy

Now, in episode four 'Hide or Seek', Tim appears in a brief, yet pretty graphic, full frontal nude shot.

His wife Victoria (played by Parker Posey) starts looking for her anti-anxiety medication, Lorazepam, all while Tim has been using it up to help him cope with the ongoing investigation.

Then in a heavily medicated state, he joins his family in their villa's living room, in a robe.

During a disoriented conversation, Tim accidentally exposes himself when his robe falls open.

His wife and children - Saxon (Patrick Schwarzenegger), Lochlan (Sam Nivola), and Piper (Sarah Catherine Hook) - were stunned, as you'd expect.

Over on X, one viewer said: "Me: *Is he completely naked under that robe?* ….yes, yes he was, I did NOT have Jason Isaacs full-frontal on my White Lotus S3 bingo card lmaooo."

"I DID NOT JUST GOT FLASH???' with a crying emoji," a second penned.

While a third added: "Did their dad just flash his balls?!!?!"

"NOT A D**K FLASH. I forgot there's at least 1 per season," someone else said.

On that very scene, Isaacs told Entertainment Weekly: "Yeah, it is now in my contract for every show I do, so we'll see. It'll get easier, hopefully."

Schwarzenegger added: "You should be asking what it was like for us to watch it."

Well, The White Lotus fans are used to a bit of nudity after season two saw Theo James flash one for the cameras, and in season one when Armond (Murray Bartlett) was caught in a compromising position with Dillon (Lukas Gage).
