Sophie Ablett has been revealed to be starring in the new series of Doctor Who. Sophie, who has also appeared in BBC daytime drama Doctors, will play the character of Marti Bridges.
Sophie joins previously announced guest stars including Jemma Redgrave and Anita Dobson. Aneurin Barnard also joins the series as the mysterious Roger ap Gwilliam. Jack Forsyth-Noble will play Will in the new series.
Jemma Redgrave returns as Kate Lethbridge-Stewart, and UNIT, the long-running organisation set on defending the Earth, returns in the next series of Doctor Who. Anita Dobson and Michelle Greenidge star in currently unknown roles.
Jack Forsyth-Noble told Doctor Who Magazine: "What an absolute treat to join the Whoniverse at such an exciting time for the show! Russell [T. Davies] has brought together a kind and incredibly talented team, and to be a part of the first day filming was really special."
The new series of Doctor Who is expected to air in the first half 2024, starring new Doctor Ncuti Gatwa and companion Millie Gibson as Ruby Sunday. The duo's first episode is expected to air on BBC One this Christmas.
Before then, Doctor Who celebrates its 60th Anniversary in November with three hour-long specials starring David Tennant and Catherine Tate.
