BBC America has launched a teaser trailer for the upcoming fantasy-comedy series ‘The Watch’ (loosely) based on Terry Pratchett’s novel.

Based on the late author’s City Watch subset of his Discworld novels, The Watch follows a group of misfit cops, led by steampunk vigilante Sam Vimes (Richard Dormer), as they attempt to save their corrupt city from unruly crime and the mythical creatures wreaking havoc in it.

Richard Dormer will be starring as Sam Vimes, Captain of the Watch, Jo Eaton-Kent as Constable Cheery, a forensics expert ostracised by her own kin, and Adam Hugil as Constable Carrot, the idealistic new recruit raised by dwarves.

Marama Corlett (Sick Note), Lara Rossi (Cheat) and Sam Adewunmi (Stan Lee’s Lucky Man), Anna Chancellor (Pennyworth), James Fleet (Outlander), Ingrid Oliver (Doctor Who), Ruth Madeley (Years and Years), Hakeem Kae-Kazim (Deep State), and Bianca Simone Mannie (Homeland) also star.
