TF1 has boarded the upcoming suspense thriller Nightsleeper, following a deal with Fremantle. Produced by Fremantle’s Euston Films for BBC One and BBC iPlayer, the 6×60 series is written by BAFTA award-winning writer Nick Leather (Murdered For Being Different) and stars Alexandra Roach (The Light in the Hall) and Joe Cole (Gangs of London).
