Laura Donnelly and Lotte Verbeek have become the latest cast additions to Starz’s Outlander, a Ron Moore series based on Diana Gabaldon’s best-selling books. It follows the story of Claire Randall (Caitriona Balfe), a married combat nurse from 1945 who is mysteriously swept back in time to 1743. When she is forced to marry Jamie Fraser (Sam Heughan), a chivalrous and romantic young Scottish warrior, a passionate affair is ignited that tears Claire’s heart between two vastly different men in two irreconcilable lives. Donnelly plays Fraser’s older sister and surrogate mother. Verbeek plays the enigmatic (and possibly witchy) Geillis Duncan, wife of the procurator fiscal.

Another straight-to-series drama, ABC’s 13-episode limited series The Black Box, has cast a duo of regulars, David Chisum and Siobhan Williams. Written by Amy Holden Jones, The Black Box centers on Elizabeth Black (Kelly Reilly), a world-renowned neuroscientist who appears to have it all but is constantly haunted by her own struggle with mental illness. Chisum, repped by Stone Manners Salners and manager Gregg Edwards, will play Josh Black, Kelly’s older brother, closest confidant and best friend. Williams plays his daughter Esme Black.
