Michael Fassbender and Keira Knightley leave viewers in hysterics with hilarious tales of 'spanking'...

Michael Fassbender and Keira Knightley had the audience of The Graham Norton Show laughing out loud on Friday night as they shared stories about making their 2011 film, A Dangerous Method.

The movie, a psychological drama, delves into the intricate connections between psychoanalysts Carl Jung and Sigmund Freud, along with their patient-turned-colleague, Sabina Spielrein, portrayed by Kiera.

The 39-year-old actress candidly spoke about the film when Graham inquired, saying, "In essence, it revolved around spanking. Michael had to give me a spank."

Michael playfully remarked, "I was the one doing the spanking, and you were on the receiving end."

Michael discussed the hard work that was put into ensuring the scenes felt authentic while keeping them from being overly distressing. He mentioned, "To find the perfect balance for the spanking, it shouldn't be too painful, I guess."

He then shared a surprising tidbit, looking at Kiera: "There was a Yellow Pages stuck between your backside and the paddle!"

On Friday night, Michael Fassbender and Keira Knightley had the audience of The Graham Norton Show laughing out loud as they shared stories from the set of their 2011 film, A Dangerous Method.

Keira was straightforward when discussing the movie, telling Graham that it focused on spanking and that Michael had to do the spanking in the film.

If that wasn't amusing enough, Keira confessed that she went out of her way to make sure the cast would always remember the experience.

"I got Michael and three other members of the cast their own spanking paddles," she chuckled. "I had to walk into a sex shop and ask, 'Hi there, could I get three spanking paddles, please?'"

Michael, who was on the show to discuss his new television series The Agency, in which he portrays a secret CIA agent, also shared that he met several actual spies to help him prepare for the role.

He mentioned, "I believe many spies are eager to reveal their true identities. Many of them enjoy watching these types of shows and are quite fascinated by them."

Fans are thrilled about a new spy thriller featuring an incredible cast, including Oscar-nominated Michael, which premiered in the US on Friday.

The Agency draws inspiration from the well-regarded French series The Bureau and was created by George Clooney and his associate Grant Heslov through their production company, Smokehouse Pictures.

The impressive lineup features Richard Gere, Jodie Turner-Smith, Hugh Bonneville, and David Harewood.

Numerous fans took to X to share their enthusiasm about binge-watching the show. Meanwhile, some immediately shared their opinions, stating: 'If you’re not tuning into The Agency on Paramount+ (with Showtime), you’re really missing something special.'

The movie is a psychological drama that delves into the intricate dynamics between psychoanalysts Carl Jung and Sigmund Freud, as well as their connection with Sabina Spielrein, who transitions from being a patient to a colleague.

Michael shared that to ensure the scenes looked realistic without being overly harsh, they placed a Yellow Pages book between Kiera's backside and the paddle, preventing any actual impact.

On Friday night, Graham hosted the iconic Cher along with Hollywood talents Michael Fassbender, Keira Knightley, and Josh Brolin, as well as singer-songwriter Jalen Ngonda on his couch.

"Paramount Plus has delivered once more! The first two episodes of #TheAgency are absolutely incredible! The cast is phenomenal, featuring talents like Michael Fassbender and Jeffrey Wright..."

The political thriller released by Paramount Plus centers around Michael's character, Martian, who is a secret CIA operative. He receives instructions to leave his covert assignments behind and head to London to meet with Richard's character, Bosko.

His professional life, true identity, and purpose are threatened when a former love from his undercover days reappears, leading to a rekindling of their relationship.

Although it aired in the US on Friday, viewers in the UK will need to wait an additional day since it is set to launch on Paramount Plus on November 30.

Earlier this month, Michael and his wife Alicia Vikander seemed more in love than ever when they left The Twenty Two in Mayfair.

The couple, who had their second baby at the beginning of the year, were inseparable as they embraced on the street while waiting for their car.

In July, Alicia shared the news that she and Michael had discreetly welcomed their second child.

In a chat with ELLE UK, actress Taylor Russell expressed her admiration for the 35-year-old Academy Award winner, stating that she was incredibly impressed by Alicia's physical performance in their new film, Hope, particularly considering that Alicia had just welcomed her second child.

Michael made an appearance on the program to discuss his latest television series, The Agency, in which he portrays a secret CIA operative.

Earlier this month, he and his wife, Alicia Vikander, seemed more joyful than ever while leaving a restaurant in London.

The Swedish celebrity stated, "Every woman has unique experiences, and facing it a second time was definitely more challenging for me."

She added, "I believe that the training played a significant role in making things smoother. Those nine months feel like running a marathon, so having strength beforehand definitely makes a difference."

"It's incredibly challenging physically, and I have a great deal of respect for any woman who has accomplished it."

Alicia shared that she had depicted the experience of giving birth in movies four times before actually going through it herself. She mentioned, "As an actor, my role is to pretend, but every time I had to portray childbirth, I found myself apologizing to all the women on set. I really felt like a fraud."

The celebrity did not share any additional information about the pair's second child.
