While writer/director Gerrit Van Woudenberg’s sci-fi mindbender Quantum Suicide references various scientific theories and namedrops physicists, you don’t need a Ph.D. to enjoy the film. Theories aside, the movie is very much about the obsession of its protagonist, Cayman, played by Andrew Rogerson. His determination to figure out the “theory of everything” unravels his own well-being and the few relationships he maintains.

Within the first 15-20 minutes, we learn a lot about Cayman, mostly that he cares about nothing else other than scientific theories. In his garage, he keeps a particle accelerator that he basically scrapped together. He spends hours upon hours in front of his makeshift machine, trying to figure out and master the secrets of the universe. All of this comes at a steep cost. Understanding the nature of reality costs Cayman his sanity and the few relationships he has, especially to his partner, Genevieve (Kate Totten).

The film references countless theories, and science nerds will likely get a kick out of that. However, like any good sci-fi film, this story grounds itself in human drama and tangible narrative beats. This movie focuses on the nature and dangers of obsession. Yes, the feature turns mind-bendy at times, especially when Cayman’s mind and body undergo severe changes. Despite all of that, the movie tells a very human story that’s timeless. Perhaps some truths are better left unknown.

Both Totten and Rogerson do just fine in the lead roles. As Cayman’s obsession deepens with each passing minute of the runtime, it’s tough not to really feel for Genevieve. She does her best to support her partner’s immense passion, but she, too, eventually reaches the breaking point. In one scene, she tells him that he’s not helping them earn any income. All he does is write down equations and loom over his machine. Rogerson plays Cayman initially like a nice guy with a super intense hobby, before his character essentially descends into madness. It’s an intriguing character arc.

The film would have been better served exploring Genevieve and Cayman’s relationship more. They’re really the most human aspect of the film. The scenes between Totten and Rogerson are some of the strongest. I just wish we were treated to more of them.

Quantum Suicide certainly isn’t some blockbuster Michael Bay-type of sci-fi film. There are no explosions or giant spacecrafts. Instead, the film explores, debates, and entertains various theories about the nature of reality itself. Yet, Cayman’s dangerous obsession keeps this feature from veering into overly heady territory. Overall, this is a smart sci-fi movie through and through.
