Millie Bobby Brown says she still 'respects' co-star Henry Cavill's 'strict' boundaries

Millie Bobby Brown has revealed that she still sticks to the 'terms and conditions' set down by her Enola Holmes co-star Henry Cavill.

The pair star together in the action-adventure films on Netflix, with Brown taking on the title role while Cavill plays the legendary detective Sherlock Holmes himself.

Enola Holmes 3 released this week (July 1) and sees Enola preparing to marry Lord Tewkesbury (Louis Partridge), however, her plans are soon thrown into chaos when Sherlock is kidnapped.

Brown, 22, had her big break playing Eleven in the hit Netflix series Stranger Things, and first took on the role of Enola when the series was between its third and fourth seasons, released in 2019 and 2022 respectively.

Now, she has spoken about the boundaries that Cavill, 43, set down and how this differed from the way things were on the set of Stranger Things.

Brown first opened up this about while promoting the second film in 2022, explaining that Cavill had set boundaries, such as not talking about his personal life.

"The funny thing with Henry and I is we’re like brother and sister, so like my big brother, he’s like, 'Millie, no, I’m not doing that,' and it’s just like, you go, 'Okay'," she told Metro.

"You’ve just kind of got to respect it because you’re like, I’m not going to argue, you know?"

The star added: "You’re just like my brother, I love you, and then I’m also like, 'No, I’m not doing that!'. I’m very much like that with Henry, but it kind of replicates my actual relationship with my brother, Charlie."

Brown had previously spoken about how this had been very 'different' on the set of Stranger Things as she and her castmates had grown up together.

"It’s different because I grew up with Noah and Charlie. I met them when I was 10. So, for me, it does feel like your schoolmates," she said in an interview with Deadline.

"And with Henry, it feels like a real adult relationship. Like a really good friendship, a really healthy one."

Describing her relationship with the former star of The Witcher and Man of Steel, Brown said: "I know Henry. He has terms and conditions with me. I’m not allowed to ask about his personal life.

"It’s like, 'Millie, shut up. No.' And I’m like 'Understood.' Whereas with the Stranger Things kids, it’s different.

"There’s no boundaries because it’s like we’re all siblings. But with Henry, he’s very strict with me, which I appreciate."

In the Enola Holmes flicks, the focus is shifted away from Sherlock to his younger teenage sister Enola. The first movie was released back in 2020, with a sequel following in 2022.

Speaking to Tudum ahead of the release of Enola Holmes 3, Brown said: "Enola still has so many stories to tell, and I’m never done telling stories.

"I was on a TV show for 10 years - revisiting characters feels very second nature to me and is always exciting. I don’t shy away from that at all."

Calling her character 'fierce, adventurous, and flawed - deeply flawed', the actor added: "I think she’s a great role model for young people, and a reminder that there’s so much more that they’re capable of."

All three Enola Holmes films are available to stream on Netflix now.
