In a delightful behind-the-scenes clip from Netflix’s Enola Holmes 2, stars Millie Bobby Brown and Henry Cavill bring their on-screen sibling chemistry to life as they attempt to build a Rube Goldberg machine—an intentionally overcomplicated contraption designed to perform a simple task. Their mission? Knock over a cup filled with Scrabble letters that spell out “Enola Holmes.”

From the start, it’s clear that the challenge isn’t just mechanical—it’s also about teamwork. Armed with dominoes, ramps, and a lot of trial and error, the pair begins plotting their chain reaction. But building the perfect machine turns out to be harder than expected, leading to plenty of laughs, light-hearted bickering, and buzzer-worthy failures.

“We just need to knock this cup over,” Henry explains, examining the precariously placed Scrabble letters inside. “So you wanna be doing it at an angle, then?” he suggests thoughtfully. Millie, ever the energetic co-star, dives into the process with gusto, knocking things over (sometimes unintentionally) and improvising with every step.

As dominoes fall short and pathways misalign, their dynamic off-camera mirrors that of Sherlock and Enola Holmes. “Sherlock and Enola’s relationship in the film is similar to how Millie and I are with one another,” Henry says with a knowing smile. “In the sense that Millie has no respect for Sherlock.”

Millie laughs at the comment, clearly reveling in the chaos. “Enola’s always been fiery. She would never just do what Sherlock says,” she adds proudly—right before their latest attempt fails with a buzz.

The duo’s banter is effortless. At one point, when a curve in the setup derails their progress, Henry points out the flaw. “What if you just went straight?” he suggests. Millie shoots back playfully, “Wait, you were the one who brought in the curve! Honestly?”

Their creative back-and-forth becomes as entertaining as the machine itself. While Henry offers a steady, analytical approach, Millie brings spontaneous energy and a flair for fun. Together, they personify the same sibling rivalry and affection that has become a fan favorite in the Enola Holmes series.

“My favorite thing about working with Henry,” Millie begins, “is that he’s really—” before being cut off by another buzzer noise as their attempt falls apart once more. Both of them burst into laughter.

Despite the repeated failures, neither of them seems to mind. In fact, the continuous tinkering and playful disagreements only highlight their real-life camaraderie. It’s clear that success isn’t the main goal—it’s the joy of the process, the shared frustration, and the mutual respect underneath it all that makes this moment so memorable.

In the end, whether the machine works or not is irrelevant. What truly stands out is the genuine connection between Millie Bobby Brown and Henry Cavill—one built on humor, collaboration, and a bit of friendly chaos. Their off-screen bond perfectly reflects the heart of Enola Holmes 2: clever, chaotic, and full of charm.
