Millie Bobby Brown Found Stranger Things Season 4 The Hardest To Film

Millie Bobby Brown has revealed why the upcoming season of Stranger Things was the 'hardest season' for her.

By the end of the first three seasons, Brown's character of Eleven had already fled Hawkins Laboratory and battled to learn more about her own telepathic and psychokinetic abilities, all while trying to make friends and figure out what love is, like any normal teenager.

However, season four of the Netflix flagship series has been the 'hardest' one yet for 18-year-old Brown; now, the actress has opened up about why she found the script so difficult compared to some of the rest of her Stranger Things co-stars.

Agreeing with Finn Wolfhard (Mike) that the show is 'constantly [...] breathing and changing' like a 'monster', Brown told Collider how season four has been 'very hard' for her.

She said: "I'm reading the script and I see Finn and some of the other characters having such a fun time, and you get to see Eleven in the darkest state she's ever been.

"This has definitely been the hardest season I've ever filmed, and there have been some of the scariest things that I've ever seen as a human, which you guys will get to see for sure.

"I'll get to tell more stories and touch on my experiences as a person filming on the set with these legitimate scary things."

As well as having to go to dark places herself in order to portray Eleven in 'the darkest state she's ever been', the upcoming season also sees Eleven's relationship to Mike grow tense because of the pair being split apart, far away from each other.

"Well, it's one of those things that it just, it's impossible. And it's with anyone. It's with having a mom or a dad or anyone. They're there. It's like air or anything. It's just like they're a part of your life. You can't just pretend it never happened," Wolfhard said.

The 19-year-old reflected on how 'in love' Mike and Eleven are and how much they've gone through together.

"Also, in an incredible way and also a pretty deeply sad way because they haven't had anyone else to like... That's what's so beautiful about [it]. It's that they don't have [a] normal life and this is the way that it is for them and that's what makes it so special," he added.

Brown noted the 'real relationship issues' season four reveals within Mike and Eleven's connection are 'really funny, and very comedic, but [...] also very real', while Wolfhard also described it as being 'tender'.

Brown explained the pair will 'always be together' and that it's more a matter of, "See you when I see you."

Volume 1 of Stranger Things season four premieres on May 27. Volume 2 is set for release on July 1.
