and Pascal Duquenne, one of the stars of Dormael's previous film The Eighth Day, also has a cameo. Production Writing The idea of parallel lives had been explored in earlier films such as Run Lola Run (1998) and Sliding Doors (1998), which influenced Jaco Van Dormael's writing of Mr. Nobody. Unlike those films, however, this one has philosophical underpinnings inspired by scientific tomes on chaos theory and the butterfly effect, pigeon superstition, and the space-time continuum. Van Dormael stated: "My starting point was a 12-minute short I made in 1982 called È pericoloso sporgersi. A kid runs behind a train with two possible choices: to go with his mother or with his father. From there we follow two possible futures. I started one version based on the fact that a woman jumps or doesn't jump on a train. Then Sliding Doors by Peter Howitt came out, followed by Run Lola Run by Tom Tykwer. I had to find something else. And that's when I realised that the story I was trying to tell was not binary, that I was above all interested by the multiplicity and complexity of choices. With this screenplay I wanted to make the viewer feel the abyss that is the infinity of possibilities. Beyond this, I wanted to find a different way of telling a story. I wanted the gaze of the child on his future to meet the gaze of the old man he has become on his past. I wanted to talk about complexity through cinema, which is a simplifying medium. While reality around us is more and more complex, the information is more and more succinct, political speeches are more and more simplistic. What interests me is complexity. Not the simple answers, which are reassuring but bound to be false." Describing the scale of the film, the director said: "My producers don't like me saying it, but it's really a big-budget experimental film about the many different lives one person can live, depending on the choices he makes. It's about the infinite possibilities facing any person. There are no good or bad choices in life. It's simply that each choice will create another life for you. What's interesting is to be alive." While producing the film, Van Dormael took the unique step of publishing his screenplay. Development The film is Van Dormael's first feature since The Eighth Day in 1996. He began trying
