The Quantum Suicide Thought Experiment

At the heart of Third Contact lies the Quantum Suicide thought experiment — a provocative idea at the intersection of quantum mechanics and consciousness. The experiment imagines a scenario in which an observer's survival depends on the outcome of a quantum event, raising unsettling questions about identity, mortality, and the nature of reality itself.

Director Simon Horrocks first explored this territory in his short film Quantum Suicide, which won the audience award for Best Sci-fi at the RATMA Film Festival in 2013. That short became the conceptual springboard for the feature-length Third Contact.

The Many Worlds Interpretation

The Many Worlds theory, first proposed by Hugh Everett III in 1957, suggests that every quantum event spawns a branching of reality — creating a vast, ever-expanding multiverse of parallel outcomes. In Third Contact, this idea is woven directly into the narrative fabric: a therapist's investigation into two mysterious deaths pulls him into a labyrinth where alternate realities may not just be theoretical.

The film uses the Many Worlds framework not as abstract exposition but as a lived, emotional experience — blurring the line between what is real and what might have been.

From Short Film to Feature

The journey from the award-winning short Quantum Suicide to the feature Third Contact was driven by a desire to explore these ideas at greater depth. Where the short posed the question, the feature lives inside it — following characters whose choices ripple across possible worlds.

Horrocks has described the film as a "five-year mission," a deeply personal project that began with a screenplay written without funding and shot with whatever equipment was at hand. The result is an independent sci-fi film that prioritises ideas over spectacle, inviting audiences to sit with the unsettling implications of quantum reality.
