The movie was shot chronologically and Willem insisted the filmmaking process was an "actor's dream."
He said: "It was a very task-oriented performance. That's where you start, by doing things, and then you'll have an experience, and with each choice you make, with each action you take, there's a consequence and then, story starts to emerge. So, it was a very organic way to work. We shot chronologically. So it was an actor's dream, actually, to work this way."
The actor hopes the movie will raise important questions about people's relationships with technology and the darker aspects of material wealth. He said: "This guy gets trapped in this place and he's surrounded by all the things we value as objects, as material, priceless art, luxurious apartment."
"But it's no use to him. What he needs are basic human things. And to see those things that we value in one context, become worthless in another context, always opens up all kinds of questions as to what their inherent value really is."
"It puts us in a questioning frame of mind about things that we take for granted, and brings us to things like questions, naturally, I think, like what is our relationship to technology? We know it helps us, but what is the shadow side of that? We know art can be beautiful. We know art can become an object of wealth, but what's the shadow side of that?"
"These sort of things crop up in the course of the movie, not in a didactic way or, not an explicit way, but those themes, I think, are kind of interwoven or, not even interwoven, they're present just in the scenario, and I think the audience will bring what they will to it, and have a dialogue with themselves."
