In this episode of Journey Through Sci-Fi, we continue our exploration of the virtual reality subgenre by looking at two films that question the nature of reality itself.
Long before modern audiences encountered simulated worlds in films like The Matrix, science-fiction storytellers were already exploring the unsettling possibility that the world around us might not be real at all.
First we discuss World on a Wire (1973), the ambitious science-fiction miniseries directed by Rainer Werner Fassbinder. Based on Daniel F. Galouye’s novel Simulacron-3, the story follows cybernetics engineer Fred Stiller, who begins to suspect that the world he inhabits is actually a computer simulation created by a higher reality.
Then we explore The Thirteenth Floor (1999), a later adaptation of the same novel that reimagines the concept through a neo-noir mystery. The film centres on a computer company that has created a detailed virtual recreation of 1937 Los Angeles, populated by simulated humans who are unaware they exist inside a digital world.
Together these films explore one of science fiction’s most profound questions:
What if our reality is just another layer of simulation?
Because here on Journey Through Sci-Fi, we explore the history of science-fiction cinema one subgenre at a time.

What We Discuss In This Episode
In this episode we talk about:
The origins of the simulated reality concept in science fiction
How World on a Wire pioneered ideas later popularised by The Matrix
Virtual worlds within virtual worlds
The philosophical question of whether simulated people could be conscious
Why simulated reality stories remain so compelling
World on a Wire (1973) – The First Simulated Reality?
Directed by Rainer Werner Fassbinder, World on a Wire is a two-part German television film released in 1973.
The story follows Dr. Fred Stiller, a scientist working on a massive computer simulation known as Simulacron, which contains thousands of artificial “identity units” who believe their world is real.
When the creator of the project dies under mysterious circumstances, Stiller begins uncovering strange anomalies within the simulation. Eventually he discovers a shocking possibility: the world he believes to be real may itself be a simulation controlled by a higher level of reality.
The film explores themes of identity, perception and technological power, making it one of the earliest and most influential explorations of simulated reality in science fiction.
The Thirteenth Floor (1999) – A Neo-Noir Simulation
More than two decades later, The Thirteenth Floor revisited the same core concept for a new generation.
The film follows Douglas Hall, a computer scientist whose company has developed a virtual simulation of 1937 Los Angeles. Users can enter the world by transferring their consciousness into digital avatars.
When Hall’s mentor is murdered shortly after discovering something troubling about the simulation, Hall enters the virtual world to search for answers.
What he eventually discovers is even more unsettling: his own reality may be just another layer within a larger simulated universe.
The film blends science fiction with noir mystery, exploring how virtual worlds might blur the boundaries between identity and reality.
Layers of Simulation
Both World on a Wire and The Thirteenth Floor explore the idea of nested realities — simulations that exist inside other simulations.
This concept has become central to many later sci-fi stories about artificial worlds and digital consciousness.
By questioning whether reality itself might be artificial, these films challenge audiences to rethink one of the most fundamental assumptions about existence:
How can we be certain that the world we experience is real?
