First look at Doctor Who legends David Tennant and Catherine Tate on BBC set ahead of epic return after a decade

DOCTOR Who legends David Tennant and Catherine Tate have been spotted back on set.

The Sun was first to reveal how the former Time Lord and his companion were making a comeback to the BBC drama next year.

The Scotsman was the doctor on the BBC sci-fi series from 2005 to 2010 and will now come back to star in a 60th anniversary special next year.

David, 51, formed one of the best-loved pairings on the programme with Catherine, 54, as Donna Noble from 2006 to 2010.

They have already got stuck into their scenes, with Catherine spotted filming while walking down the street.

She couldn’t be missed in a pink and red striped jumper paired with dark trousers.

Meanwhile David could be spotted in a smart suit and tie.

He appeared to crack a joke as he stood alongside the blue Police box Tardis, giving fans a hit he may well time travel again.

He then frowned as he scanned the cast before getting set for another take.

Announcing the pair’s return, showrunner Russell T Davies said: “They’re back! And it looks impossible — first, we announce a new Doctor, and then an old Doctor, along with the wonderful Donna, what on earth is happening?

“Maybe this is a missing story. Or a parallel world. Or a dream, or a trick, or a flashback.

“The only thing I can confirm is that it’s going to be spectacular, as two of our greatest stars reunite for the battle of a lifetime.”

The announcement comes just a week after the BBC confirmed that the actor taking over the Tardis from current doctor Jodie Whittaker, 39, would be Ncuti Gatwa, 29.

Jodie’s final episode is set to air in October.

Russell was the showrunner who rebooted the series in 2005 with Christopher Eccleston, now 58, as the time lord.

He then signed up David for the part when he was a little-known actor.

But he went on to be one of the most popular doctors, regularly attracting huge viewing figures for the show.

He went on to win wide acclaim in shows including Broadchurch and playing serial killer Dennis Nilsen in drama, Des.
