"Cut!" Christopher Nolan called out. "That's a wrap for this section. Matthew, take half an hour. Next group, on set!"
As Matthew stepped off the set, Nolan turned to him and asked, "How are you feeling? Do you need a stunt double?"
"I'm fine." Matthew gave Christopher Nolan a thumbs-up.
"I've trained extensively. I can handle these scenes."
The action sequence, while certainly complex and not without its risks, was well within his capabilities.
He performed in most of the scenes himself, relying on a stunt double for only the most dangerous sequences.
Christopher Nolan didn't press the matter. The risks weren't extreme, and having the actors perform their own stunts significantly reduced the challenges for post-production.
Though the action scene they had just filmed was brief, Matthew still made his way to the rest area.
Matthew took a short break, but filming continued without pause: James McAvoy started shooting the scene where Arthur levitates.
As the hallway set began to rotate and tilt, the wire-suspended actors would instinctively adjust their balance. Meanwhile, a fixed camera created the illusion that the direction of gravity was changing. Many of the props, including the walls themselves, were constructed from soft materials to keep the actors safe within the spinning structure.Executing the action sequences was challenging, but the risk of injury was relatively low.
The half-hour flew by. James emerged from the set, breathing heavily, and it was Matthew's turn to start filming again.
The shoot here was for one of the film's most unique sequences, a blend of practical sets and digital technology.
When the morning shoot wrapped up, Matthew noticed Christopher Nolan hadn't gone to lunch. Instead, the director was still in his chair, reviewing the morning's takes.
From the start of production, Christopher Nolan had given him an open invitation to review the footage.
Christopher Nolan was also aware that Matthew was branching out from acting into producing. A producer didn't need to master every technical craft on a film set, but a comprehensive understanding of the entire process was essential.
So, whenever Matthew had questions, Nolan was happy to answer them to the best of his ability.
Matthew greeted Christopher Nolan and moved to stand behind him.
He hadn't been able to appreciate it fully while in the midst of filming, but now, seeing it from an audience's perspective, the zero-gravity shots looked truly ingenious.
Matthew was well aware that his own knowledge of filmmaking and producing was still developing. He never felt embarrassed to ask about things he didn't understand. "Chris, how did you create the weightless effect here?"
Christopher Nolan glanced at Matthew, then pointed to the playback screen. "You mean how we get these shots to convey that sense of zero gravity, right?"
Matthew smiled and replied, "Yes."
"There are two main ways to shoot scenes like this in Hollywood. The traditional approach involves building a high-speed, rotating centrifugal set, allowing the actors to perform in a genuine state of weightlessness. The digital approach, on the other hand, considers that too much trouble. Their method is to simply hang the actors on wires in front of a green screen and composite them with the background later."
Matthew nodded thoughtfully, waiting for him to continue.
"However, I find both methods have their shortcomings," Christopher Nolan said directly. "My approach relies on a seamless blend of practical sets and digital technology—a marriage of a director's vision and cutting-edge digital tools."
He paused the playback and pointed to the background. "First, the entire scene was shot on a practical set, where the actors, yourself and James included, were suspended by wires to simulate weightlessness."
Matthew followed up, "But that kind of suspension is more complex than it looks. You can't just run a few wires and call it a day, right?"
Christopher Nolan nodded. "Shooting it the conventional way would create a post-production nightmare, requiring a tremendous amount of wire removal. So, I devised a much better method: we built the horizontal set vertically and filmed with the camera pointing straight up."
"The walls on either side of the hallway effectively become the ceiling and the floor. The horizontal axis of the scene is now physically vertical. This way, the suspension wires hang straight down. From the camera's perspective, they appear to extend from the sides of the hallway instead of dangling from the ceiling."
"So that gives the actors a much better chance to conceal the rigs, which must save a ton of work in post?" Matthew asked.
"Exactly," Christopher Nolan confirmed. "In that regard, practical shooting methods ended up doing digital technology a huge favor."
Nolan switched from the finished effects shot to a raw take featuring Ken Watanabe and Cillian Murphy.
Nolan watched the clip for a moment before saying, "Matthew, not every actor can handle these action sequences as smoothly as you do. It's difficult for some, especially when they have to face the camera, which means they're physically facing down during the shot. They can't hang there for an entire long take, so we use stunt doubles. But, of course, we still need to see their faces on screen..."
"That's where face replacement becomes necessary. It's something that can only be achieved with digital effects. The VFX artists scan the actor's face, create a digital model, and then graft it onto the stunt double's body."
Matthew understood his point. "So practical filming and VFX technology go hand in hand, blending seamlessly."
"Precisely." Christopher Nolan affirmed.
This conversation with Christopher Nolan helped solidify an important idea for Matthew: practical and digital effects shouldn't be seen as competitors. While digital effects were the way of the future, practical techniques still had a vital role to play, and the two could be used to complement each other powerfully.
Top-tier Hollywood productions weren't about a battle between practical and digital, but about the integrated use of every tool in the filmmaking arsenal.
