Jodie Whittaker ’s big Doctor Who finale will see her don a mash-up of the iconic costumes worn by many of her Time Lord predecessors.
And it will also see a comeback for Bradley Walsh as former companion Graham O’Brien, who returns to help her meet up with old friends and battle her oldest foes.
Whittaker’s feature-length swansong as the 13th Doctor is timed to be part of the BBC ’s huge centenary celebrations in October.
