How a failed spec script evolved into a four-season time travel epic

In short: Originally titled Splinter, a spec script about time travel caught the attention of Atlas Entertainment, the producers behind the 1995 film 12 Monkeys. What began as an attempt to adapt that movie transformed into a complete reimagining, spanning 47 episodes and a complex, pre-planned narrative arc.

The series 12 Monkeys, which premiered on Syfy in 2015, was created by Terry Matalas and Travis Fickett. While it shares DNA with the 1995 film and Chris Marker’s 1962 featurette La Jetée, the show quickly diverged into an original storyline. The pilot episode effectively covers the film's premise, but the subsequent narrative follows a distinct path. Matalas and Fickett, who had previously collaborated on Nikita and Terra Nova, designed the series with a definitive, emotional ending in mind from the very beginning. They initially plotted three seasons but eventually determined that four were necessary to fully realize their vision.

Production was a global undertaking, moving from a Detroit-based pilot to extensive filming in Toronto, where the show utilized Cinespace Film Studios. To capture authentic period aesthetics, the crew later filmed in Budapest and Prague, leveraging European architecture to stand in for various historical settings. The production team also employed sophisticated visual techniques to differentiate timelines. The bleak future of 2043 was rendered in constant blue and green tones, influenced by the film Children of Men, while the present-day timeline utilized a broader color palette.

The show's technical execution earned significant acclaim, particularly for its cinematography. Led by David Greene and Boris Mojsovski, the camera team utilized digital 1080p workflows, transitioning from Arri Alexa Classic cameras to the Alexa Mini. Their collaborative approach was so seamless that the cinematographers often could not distinguish which of them had shot specific scenes. This artistry was recognized by both the American and Canadian Societies of Cinematographers, which collectively awarded the series two honors and four nominations for its visual craftsmanship.

The story follows scavenger James Cole, played by Aaron Stanford, who is sent back to 2015 to prevent a global plague. He is joined by virologist Dr. Cassandra Railly, portrayed by Amanda Schull, as they navigate a web of conspiracies orchestrated by the Army of the 12 Monkeys. The series concluded its 47-episode run on July 6, 2018, maintaining a consistent narrative thread that circled back to its origins.
