Actor James Corden of Gavin & Stacey fame will guest star in the fifth series of Doctor Who according to a rumour in The Sun.

The paper reports that Corden was ‘spotted learning lines while on a train to the Who set in Cardiff.’

“We normally keep our guest stars under wraps but you can’t hide a bloke like James”, said an apparent ‘show insider’.

“We’re just delighted to have James on board. He is a great actor and he’ll be a perfect fit for the new Doctor Who.”
