Three new cast members have been added to the new series of Doctor Who, and at least one of them will be a familiar face to TV viewers who love a bit of an oul' quiz.

Bradley Walsh has most recently enjoyed success as the host of The Chase, but he'll return to acting as Graham, one of three companions of the new Doctor, Jodie Whittaker, when the 11th series kicks off.

Joining Walsh as one of the Doctor's friends will be Ryan, aka actor Tosin Cole, who played Lieutenant Bastian in 'Star Wars: The Force Reawakens'. 

Former Doctors and Hollyoaks actress Mandip Gill will also play a character called Yasmin.

The news has gone down pretty well with fans of the sci-fi series, who are welcoming such a diverse group of actors as co-stars of the first female Doctor - although some of more hardcore fans are questioning the fact that there are three companions, as opposed to the normal one.
