Set in the very near future where scientists have discovered a method of matching people with their perfect romantic fit using DNA, eight-part Netflix Original The One is technically a sci-fi drama. Really though, it’s a crime thriller revolving around the murky circumstances in which the cash cow company behind the matching service was created. Written by Misfits and Crazyhead creator Howard Overman, The One is based on the 2017 novel of the same name by John Marrs. It’s a cat-and-mouse game between wealthy, driven CEO Rebecca (Hannah Ware) and police detective Kate (Zoë Tapper).

While you’re solving the show’s mysteries, we’ve taken the liberty of solving that nagging background question of where you might have seen its cast on screen before…

Hannah Ware – Rebecca Webb

The One Hannah Ware as Rebecca

Prior to The One, actor and model Hannah Ware’s biggest roles were over in the US. She starred opposite Sean Penn as an astronaut in Mars-landing sci-fi drama The First, played the drug-addict daughter of Kelsey Grammer’s mayor character in Starz political drama Boss, and played the co-lead in ABC relationship drama Betrayal, which was cancelled after one season. Film-wise, Ware played top assassin Agent 90, Katia van Dees in 2015 feature Hitman: Agent 47, based on the videogame series. She’s the sister of British singer-songwriter Jessie Ware.

Stephen Campbell Moore – Damian

War of the Worlds Stephen Campbell Moore

Stephen Campbell Moore’s other most recent TV role is in War of the Worlds (pictured above) another Howard Overman-written series produced by Urban Myth. In that he plays Jonathan, a married father who’s stranded in France when aliens invade Earth, who has to find his way back to his family in the UK. His highest-profile film role was probably in 2019’s Downton Abbey movie, which came after 2006’s The History Boys, 2011’s Johnny English Reborn and Nicolas Cage actioner Season of the Witch. He’s had plenty of TV roles, including BBC period military drama The Last Post, The Child in Time with Benedict Cumberbatch, the Titanic TV series, Hunted, Our Zoo, The Wrong Mans and many more.
