Lynda Baron to star alongside James Corden in sixth series of 'Doctor Who'.

Lynda Baron is set to guest star in the sixth series of 'Doctor Who'.

The 'Open All Hours' actress - who played vivacious nurse Gladys Emmanuel in the '70s sitcom - is reportedly due to appear opposite actor and comedian James Corden in an upcoming episode of the BBC One sci-fi drama.

With 'Gavin and Stacey' star James reprising his role as landlord Chris Owens, who provided a home for the time-travelling Time Lord - played by Matt Smith - when he investigated a bizarre alien time machine in series five, Lynda's appearance will mark her third time on 'Doctor Who'.

The 71-year-old actress first appeared on the show in 1966 when she sang the 'Ballad of the Last Chance Saloon' in one-off episode 'The Gunfighters', before returning in 1983 to star in the sci-fi serial as Captain Wrack in the 'Enlightenment' storyline.

In addition to Lynda's rumoured appearance in the show, leading man Matt Smith recently revealed a whole host of other famous faces - including model Lily Cole, comedian David Walliams and 'Downton Abbey' actor Hugh Bonneville - are set to star in the upcoming series of 'Doctor Who'.

He said: "I do think we've got one of the greatest monsters, especially during my tenure on the show, but I think in the history of it, it's a real cracker.

"We've also got some great guests stars. We've got Lily Cole, Hugh Bonneville, David Walliams, so it's really exciting."
