No rehearsal? No problem. To deliver an authentic performance in Netflix’s The Woman in Cabin 10, Keira Knightley did not rehearse any of her scenes. The decision not to walk through any of the sequences beforehand came from director Simon Stone, who emphasized spontaneity on set.

“Keira’s performance doesn’t feel fake at all,” Stone told Digital Trends about the lack of rehearsal. “You go, ‘Oh wow. She’s really reacting to stuff.'”

Based on Ruth Ware’s 2016 novel, The Woman in Cabin 10 follows Lo Blacklock (Knightley), an investigative journalist who finds herself covering the lives of the wealthy guests on a superyacht. One night, Lo witnesses a passenger being thrown overboard. Much to Lo’s surprise, no one believes her. Something nefarious is going on below deck, and Lo must find out before it’s too late.

Ahead, Stone explains how the film can be appreciated by everyone, even for those who didn’t read the book. He also discusses his background in theater and why he chooses to avoid rehearsal.

This interview has been edited for length and clarity.

Digital Trends: Anytime I watch a thriller with a mystery at the center, I feel like I’m always trying to play detective and see if I can solve it before the big reveal. This movie is based on a novel. When you were first looking at the material, were you able to solve the mystery before it happened?

Simon Stone: No. 

You couldn’t piece anything together?

I think there are two different things. There’s a ticking clock in a film. I think in a book, you can put it down, and you can go, “Well, I reckon these are the five options of what’s happening here.” In a film, the film keeps going. Even if your brain is going, “Hang on,” the other part of your brain is trying to keep up with the movie that’s actually happening. 

That’s the fun thing about the film. I think a lot of people have read the book who may or may not remember what the twist is. Even for those audience members [who read the book], it’s a fun thing to figure out how the heck we managed to pull it off, which is pretty miraculous in and of itself. But also, I think such a pretty significant audience for this won’t [know the twist]. 

There is an overlap between people who read bestseller thrillers and people who watch Hitchcockian movies. I think there are significant parts of that Venn diagram that are free for people who have no experience with that book and are going to find it genuinely shocking. I still get questions from people who knew what the premise of the film was about and how we pulled it off. They genuinely can’t figure it out.

In the notes I was reading, Keira said you didn’t like a lot of rehearsal in this film. I find that interesting because of your background in theater, a medium that relies on rehearsal. 

Well, I don’t rehearse in the theater either. 

Can you explain why?

In a film that’s about people being surprised and shocked, you lose something, don’t you? Everyone agrees with each other on how they do it. “OK. I’m going to walk through the door, and then you’re going to be scared.” I mean, that is a game my daughter likes playing with me. I’m not sure how convincing I actually am when she walks through the door pretending to be a monster. The more you rehearse it, the more it loses a kind of fire to it. 

Also, I love mistakes. Mistakes are like my favorite thing in art. For me, whenever I see a mistake, it feels like an extraordinary moment. If you try to repeat it, you can’t. If you weren’t rolling when it happened, you just go, s***, we should’ve just shot that. And people say, “Well, we should have shot it after rehearsal.” 

You don’t have to do that anymore. We’re filming on digital. You can literally shoot it. Why would you not press record, even if there are lights in the shot? It’s because people want to protect themselves from making a mistake. If the focus is out or whatever, you don’t want the director to be able to use that, so it’s a self-protective mechanism that people have. We don’t want to rehearse the camera moves or know where the actor is going to stand. 

But I keep walking in and pulling up marks that people had sneakily put down, and they conspiratorially agreed that the stand-ins would tell the actors where they’re supposed to stand so that they could get the focus right. I was like, “No, I want to see someone straining to get the focus right.” I want to see that buzz where, for a second, it goes out, then it comes in; that’s all the subconscious stuff.

Now, it would be s*** if people were pretending to do a fake focus in a mockumentary or whatever. I find that annoying. What I find is that if you get the miracle of an extraordinarily well-shot film, and I think you’ll agree that it’s beautifully lit, it looks like a thriller. It’s epic in scope. 

There are shots that look tailor-made and rehearsed; they’re not. Even the shots of the boat in the fjord in Norway — it’s me talking to the drone pilot while he’s doing it, going, “Yeah, go a bit to the left. Go down. OK, now do that.” And talking to the boat captain, going, “Could you speed up a bit? Could you slow down a bit? Can you turn to your left now?”

I’m talking to three different boats at once, and that’s me just improvising. That requires a great level of responsiveness and a kind of spontaneity on the part of everyone, and really staying in the moment. What you get out of it, and I’m sure you’ll agree, is that Keira’s performance doesn’t feel fake at all. You go, “Oh wow. She’s really reacting to stuff.” That’s a kind of strength that you get [when you don’t rehearse], and I would sacrifice any track being slightly wonky or whatever for the beauty of that. 

The Woman in Cabin 10 is now streaming on Netflix.

Apple announces new sci-fi film Liminal and I can’t wait for it
A strong cast and graphic novel roots make this new Apple film hard to ignore.

Apple just revealed Liminal, and it already looks like a serious contender for its next big sci-fi movie. With a clear sci-fi hook and recognizable names attached, this is the kind of announcement that’s easy to get invested in early.

The project comes from Apple Original Films and pairs Vanessa Kirby with Yahya Abdul-Mateen II in leading roles. It’s directed by Louis Leterrier, who’s known for keeping stories fast and visually sharp, which already hints at a more kinetic kind of sci-fi than Apple usually leans into.

Harry Potter TV series’ first trailer is out and it feels like a replay I didn’t ask for
HBO had a chance to reinvent Harry Potter, but this feels like a visual rerun.
hbo-harry-potter-tv-series

Well, HBO has finally dropped the first trailer for its Harry Potter TV series, set to premiere this Christmas, and it brings you right back to the beginning. That's broadly the only source of a vague intrigue for me, and I'm being generous here. Yes, it sets the stage for what should be a bold reinterpretation of the Harry Potter world. The trailer, however, settles for a safe, almost unimaginative retread.

Alright, so what am I looking at?
