Produced by Eleventh Hour Films and distributed worldwide by Sony Pictures Television, “Alex Rider” is based on the bestselling book franchise written by Anthony Horowitz, which has sold more than 20 million copies worldwide. The series follows Alex, a teenager who has unknowingly been trained since childhood for the dangerous world of espionage.

Horowitz serves as an executive producer alongside Eleventh Hour’s Jill Green and Eve Gutierrez, series writer Guy Burt, director Andreas Prochaska and actor Otto Farrant.

The company also adapted Horowitz’s bestselling novel “Magpie Murders” as a six-part drama starring Lesley Manville for PBS Masterpiece and BritBox U.K. The property, and its sequel “Moonflower Murders,” has found a new home in the BBC. Together with Boatrocker and Luti Media, Eleventh Hour is in post-production on “Robyn Hood,” a Canadian-set contemporary reimagining of the British legend for Corus.
