Doctor Who star Jodie Whittaker stuns pupils with surprise appearance at Sheffield school

This is the jaw-dropping moment new Doctor Who star Jodie Whittaker stunned pupils at a Sheffield school – by jumping out on them as they watched a sneak preview of the show.

Students at Wales High School were left open-mouthed when the star leapt out from behind a screen as they were given a glimpse of the Sheffield-filmed show which airs for the first time on Sunday.

Dressed in full costume, the actress yelled ‘boo!’ as she started groups of youngsters at the school in Kiveton Park who thought they were simply being treated to a first look at the new series.
